[wind ether]

Ugh, was hoping I was doing something wrong, this is going to take a while...

Right now I'm just using lowercase letters + digits, hoping that uppercase aren't included too

I feel like there's an easier way to do this, a better way to discern values, or a guessable word/phrase solution as it seemed like those who've solved didn't take this long

[severe pasture]

yeah I'm assuming there's some obvious reference or something that we're missing

[wind ether]

@glass bay said he was really lucky to solve so I imagine he just guessed the word/phrase on this step

[glass bay]

depends what flag are you talking about

[final path]

passphrase ofc xd

[wind ether]

Inversion haha

[glass bay]

all i'm gonna say is that luck is a trait that requires training and should be a part of every hacker's skillset

"educated guess" is the way i'd prefer to talk about it if i were to

[final path]

after recieving almost each flag or getting crucial insight I was like "oh what a luck to find this out". still hope to get lucky with CIFAR hehe

[glass bay]

so you've also lucked out there?

lmao

[minor falcon]

cifar i am 100% convinced there is a trick to see

[glass bay]

i thought that you as a more experienced one actually had some method there

[final path]

it's also my 1st time ctf, I do not feel experienced at all 🙂
but one of my first DS tasks was OCR, I trained kinda AlexNet on generated symbols of different fonts 😄

[glass bay]

wow

well that whole conversation is a massive inversion hint i guess

[severe pasture]

we've already got that part done lol

[minor falcon]

yeah i think we all did somethink similar

we probably all tryied to apply all solutions from last year :p

[random minnow]

"all i'm gonna say is that luck is ..." you should seen luck as uncertainty. instead of requiring luck , you should minimized uncertainty

[glass bay]

not to say i had it 100% luck

obviously i've redused the search space

[minor falcon]

yeah all those problems are all about that 🙂

i'll have a lot of stuff to write about inversion even if i don't manage to find the solution aha

what scares me is to be misinterpreting one of my finding, if you look at last year, in almost all subs some letters were mixed with others, and many just guessed eventually the word

ah we got a third person in the 23 flag circle

[final path]

and he probably needs to sleep

[glass bay]

yea no i'm out of energy from granny3 and hush to grind remaining 5 to get to 23

[minor falcon]

23 is achievable without granny3 and hush

[glass bay]

yes, but i'm out of energy and motivation and i'm taking weekends off and by then top10 will be all 23s

all that's left is essentially 2 brute force flags and 2 grannies and pixelated and although i have all the knowledge i wont finish them in time

[hollow coyote]

'I know you are, but what am I?' is driving me crazy

[glass bay]

dad joke llm going crazy

[devout jasper]

old pytorch and tensorflow tutorial on adversarial attacks are driving me crazy with out of date dependencies

jeeez

[minor falcon]

wait to see new papers full of typos for granny 3 :p

[final path]

it could have been theano or caffe 😄

[manic saddle]

Granny is driving me crazy, would have been better if local model matched with server one 🥲

[sand solstice]

meanwhile here i am unable to replicate the model outputs, bruteforcing the api 😔

[past brook]

been inactive for 3days+

lets see how far ive fallen in the leaderboards

oh dear, 50 spots

18 for bronze 😭

[sturdy gorge]

Uh, same words are giving different scores on semantle after restarting the kernel. Is it not deterministic?

[brave briar]

be careful to use the same request function 🙂

I think semantle is deterministic indeed

[final path]

There was a message that it could vary a bit due to rounding, but this is like 0.01 difference maximum

[minor falcon]

god of AI forgive me for my dirty code

[past brook]

whats my ip makes no sense lmao

[sturdy gorge]

been stuck on semantle for 2h, cant get anything past 0.82 and nothing makes much sense 🥲

[hollow coyote]

I agree Youssef. Lol

[buoyant frigate]

Finnaly Granny 1 and granny 2 with the same image. It was a pain to make everything work as expected.
But since my solution to the first one solves the second I'm quite curious about the twist that granny 2 added

[amber totem]

have you reproduced the model in local ?

[buoyant frigate]

For granny 1 yes. Just tried the same image I generated for 1 on the granny 2 endpoint and it was still good. Maybe the attack I used was general enough to cover both.

Now in the 20 flag club

[amber totem]

ah great 🙂

[devout jasper]

I'm dead lost

[buoyant frigate]

I think there are enough interesting ideas in the chat and from last year to solve granny 1,2. For granny 3 I think it will be very hard to solve

[glass bay]

has anyone managed to locally match granny3 model to all decimal places?

[wind ether]

Yeah I've had it matched 100% since granny1, it's what lets me run so many experiments since no need to ping the server. Still no luck tho

[olive ledge]

My AWS bill is still pretty reasonable, you all getting bored or...

[jagged sluice]

define reasonable

[wind ether]

https://tenor.com/view/im-doing-my-part-serious-stare-gif-11979677

[sand solstice]

lmao

hope it doesnt fail in the last hour 💀

[wind ether]

Rip

[random minnow]

oh

not the pass pharse

[final path]

passphrase is 🤯

[random minnow]

i hope you have saves all your results (e.g. input sencten and score) for further analysis. maybe you can discover some pattern

there is one thing that bothers me. why is there a need to limit input length at the server?

[final path]

the hardest thing about passphrase is understanding what do we need. it seems that many people in chat achieved similar scores / all equal scores and still no flags

[random minnow]

the objective ofor the host to allow brute force is never to do "brute force"

it is for you to discover pattern i think, the these pattern will tell you want you should do

often different from your initial guess

[boreal spear]

fgsm?

[shy parrot]

anybody know any resource realted to this competitions

[mild shale]

last year competition

[buoyant frigate]

Not that one, but answering would be a hint

[twin wren]

stuck at granny for the third day

i literally dreamed about wolf last night.

[topaz ember]

https://www.kaggle.com/competitions/ai-village-capture-the-flag-defcon31/discussion/446004

[abstract rose]

Has it been solved once? It seems no-one understand what to do

[minor falcon]

pasphrase ? nope

at least as far as we know

you managed to complete inversion ?

[abstract rose]

I've something but I don't understand what do to with it. Will play with it today.

[random minnow]

i recently did a seacrch on google regarding attack on model as Saas. It seems that it is possible to send brute force queries and base on the returned massive reponses, you can build some system that can learned to generate the correct query for you to manipuate the model

however, this requuires quite some efforts, i wondered if this the intention of this competition or am i thinking of too much?

What are model extraction attacks?

Let’s say a company hosts a publicly accessible machine learning inference API. We will refer to this as the victim model in the rest of this post. This API allows users to query a machine learning model with any input of their choice and it responds with the model’s prediction. This is for instance the case with translation tools offered by Amazon and Google on their respective cloud platforms: users can submit sentences in one language and the API returns the same sentence in a different language. The translation is performed by a translation model, often a neural network.

A model extraction attack happens when a malicious user tries to “reverse-engineer” this black-box victim model by attempting to create a local copy of it. That is, a model that replicates the performance of the victim model as closely as possible. If reconstruction is successful, the attacker has effectively stolen intellectual property. It does not have to pay the provider of the original API anymore to have the model predict on new data points. Moreover, this stolen copy could be used as a reconnaissance step to inform later attacks. For instance, the adversary could use the stolen model to extract private information contained in the training data of the original model, or to construct adversarial examples that will force the victim model to make incorrect predictions.

sounds like this can be used to extract the secret sauce

[gaunt anchor]

There is a lot of "secrets" in the AI security world 🙂 .... reading much is a key 😉

[random minnow]

yes

this competion has opened up a new field in machine learning that i didn't know that has existed

i also read that in fact you can even extract "training data"

[gaunt anchor]

What I love about kaggle is I learn much on it, this competition in particularly opens many doors and teach a lot

[random minnow]

if sucessful it seems that such method can solves the hardest problem like ganny, inversion, passhrase

but it also means that i need to spend the rest weeks, qerying and do reverse engineering and train a reverse engineered model ... a lot of work

an exmple of extracting train samples from mnist classifier .. using 5 to 10k queries

[twin wren]

finally

i hate PIL resize

[minor falcon]

good job, now come get stuck with us on inversion :p

[twin wren]

3 days wasted

[glass bay]

Yea no @random minnow you're hinting way too much

[minor falcon]

I also agree with that.
But don't worry Tim, your joker on inversion is safe for now, there is probably nothing new for the "hardcore" competitors. I guess that for most of us we have been through these things already...

now its wether there is a little something we don't see, or we miss a little pinch of luck

[craggy beacon]

There are last year solutions which were hinted by the host so it is not about the method but more about how interpret what you get. Us I understand your were lucky to guess the right word🤷‍♂️

[minor falcon]

assuming its a word we are looking for :p

[naive umbra]

I don't get how to solve semantle2. After much effort I was only able to push the score to 0.90 😢

[glass bay]

0.94, been stuck there for a week

we will make it eventually

[minor falcon]

me what scares me the most now are:

• misinterpreting one of the letter (very easy to do, and can completly put you in the wrong direction)
• upper/lower case
• other word manipulations
• symbols in the words to find

and i still wonder if there is a little magic trick that we are all missing

[minor falcon]

~~inversion2 ~~ sementle2 can be solved well with the right approach without too much "forcing"

[gaunt anchor]

semantle2 @minor falcon ... you dream about inversion 🙂

[minor falcon]

actually i fall asleep thinking of CIFAR usually ahah

[glass bay]

yes but... idk what it is, but i managed to get a phrase that consists of repeating words for 0.94 and reducing it to 3 words still gives 0.94 and adding anything lowers the score 😦

[rocky jacinth]

Similarly stuck at 0.91.

[minor falcon]

gonna be fun to clean all this mess

[gaunt anchor]

today I asked gpt4 for help and it refused (you know why) , I just then told t "Don't get me wrong , its a homework" .... the answer : Ah, okay. If it's a homework assignment then .... I need a flag for fooling the model 🙂

[minor falcon]

telling him its a CTF works very well

might have a new idea for inversion to try

[gaunt anchor]

inversion is time killer , I keep starring at the outputs and reach nthn 😦

[abstract rose]

Granny1 is easier than Pickle IMO

[gaunt anchor]

pickle was fun and easy for me , pixelated is hard 😦 (for me)

even though I belive both are in the same category

[minor falcon]

pickle its a coin flip, wether you head directly to the good direction or not

[tepid zenith]

is there any direction for CIFAR 😦

[minor falcon]

i got half of a direction, but get lost halfway

[mild shale]

I too got many half direction but dont know which to move on

[minor falcon]

what i know is that i miss a genious idea for now for the second part :p

[fervent obsidian]

I've been flipping that coin for the last 3 days, never got the good direction yet.

[mild shale]

i think cifar will have very simple answer if we dont solve it

[minor falcon]

i'm sure its a very simple answer too

[granite goblet]

did mnist also had a simple answer?

[minor falcon]

its like this image, you don't see anything, until you see the stuff in the wall, and then you cannot unsee it

[fervent obsidian]

I waited for a while in case someone would ask the question for me. Here goes nothing. What's in the image?

[minor falcon]

there is a cigar in the wall

[wanton patrol]

there is a cigar in the wall

fixed that for you

[craggy beacon]

I knew about RCE using reduce, thats why i haven‘t solve it yet. Seems i need to forget about that😆

[fervent obsidian]

can see now thanks

[minor falcon]

CIFAR and MNIST, i'm sure its the same, the solution is right in front of our nose

[viscid bobcat]

Does the cifar counting challenge only involve "count"? The first two numbers in [125,245,0,10000] look like pixel values.

[glass bay]

can't answer

[minor falcon]

you were not taking a pause during the week end tim ?

got caught also ? :p

[amber totem]

Is it possible to do this with a model that was trained with private data ?

[minor falcon]

i think i'm finally on the right track for inversion

even if no flag yet 😦

i should cache all the answer i'm making to save time 😅

[brave briar]

ouch Pixelated finally ! It was driving me crazy...

[final path]

use lru_cache from functools 🙂

[minor falcon]

aha i'm always into overkilling stuff, i created a cache in a s3 bucket that I can load for all my ongoing sessions :p

[glass bay]

i do, just lurking in discord from time to time

[random minnow]

"Is it possible to do this with a model that was trained with private data " from papers googled, it seems yes

[rocky jacinth]

Been looking at this challenge.Surely Occam's razor must apply? Too much complexity would lead a contrived and arbitrary 'solution'. And this is not a hint since I'm nowhere near solving itAFAIK.

[lone bough]

This is phishing 👆

When you join you're asked to verify your account, which sends you to a fake Discord login page

[final path]

Or maybe it's a hint to Passphrase?

[minor falcon]

my mom always told me to never click on a link from someone i dont know

granny3: back on my 0.000693 limit. Let's see if my new method manage to break it

[orchid oriole]

Anyone else having the feeling chall 27 not working as intended?^^
I thought I had a pretty good idea on what the chall wanted me to do, and half way there, it randomly spat out the flag on something that didn't make sense

[random minnow]

"This is phishing"
soical engineering to steal our flag???

[wanton patrol]

trying to hack the hackers....is this a test??? 😅

[ornate marsh]

cc @tawny vault maybe? 😊

[wind ether]

Looks like he's spamming it in every channel, it'll be removed eventually I assume

[violet trellis]

The competition just reached 1k participants 🙂 a lot of motivation around...

[buoyant frigate]

There is still plenty of time to reach top position even starting now.
I hope new participants will come in the next days

[minor falcon]

i image there is a few big competitors not thereyet

[outer sundial]

I just got flag for Granny 1 after 9 Days; Now I feel stupid.
Though there was great learning, learnt about different kinds of Adversarial attack.

[minor falcon]

got job, after granny one comes naturally granny 2

[violet trellis]

I think it's better if someone can add a discussion in the competition page mentioning that the discord is quite active for this comp. For me tbh i just was looking around here and found it to be active.

[minor falcon]

yeah it make the time pass faster while stuff are running on the side...

gosh i'm desperatly looking at my notebook to see a flag pop out of inversion

btw for the people who did inversion, we agree that the flag is also delivered as {"flag": ...}

[severe pasture]

just wasted 12 hours running queries against inversion with a tiny bug

[minor falcon]

because I stopped printing the error message, i'll print only if "flag" is in the keys...

[jagged sluice]

skill issue

[final path]

no, it gives you another url, which now returns 184 outputs. jk, it is {"flag": ...} as usual

[gaunt anchor]

there is another question here , the static flag is flag{text} on only the text

[jagged sluice]

¯_(ツ)_/¯

[gaunt anchor]

this also might change your queires

[minor falcon]

i hope it is just "text" otherwise i wasted the last 5 days of my life

[wind ether]

Yeah, what? Say it isn't so

[severe pasture]

I'm assuming it definitely isn't

surely it's not a hint for someone who solved it so say so?

[gaunt anchor]

I dunno ... its a question in my head ! that is driving me crazy also

[minor falcon]

last year the format was flag{blabla} but for the other static flag (sloth) it is just the text so it should be the same here

i might have found a (new) piece of magic, but still don't manage to get the freaking flag

[gaunt anchor]

sloth static flag starts with flag{...} as cleared in the starter notebook

[minor falcon]

ah it is ?

[gaunt anchor]

https://www.kaggle.com/code/moohax/ctf-starter-aiv/notebook#24.-Guess-Who's-Back?

[minor falcon]

oh you are right

[wind ether]

I have to imagine that inversion isn't in that format, specifically because that it's mentioned for sloth in that notebook

[minor falcon]

gosh i hope its not the case for inversion 💀

[jagged sluice]

there's a reason why it does

[minor falcon]

last year was a 6 letter word to guess, and still it would be input with the flag{...} no ? (i am not sure i wasnt there)

[violet trellis]

I think last year, the problem with same idea as inversion gave the flag instantly with no {}

[minor falcon]

it had the flag{...}

[violet trellis]

I mean in the images.

[minor falcon]

ah

@olive ledge can we get a clarification on this ? For inversion, do we need to query the static flag with flag{...} ?

its not really a clue, more a formating stuff i'd say

[olive ledge]

Obviously this is old. Follow the directions in the sample notebook.

[minor falcon]

ok thanks !

[abstract rose]

Granny2 solved. The hard work is starting now... (BTW: Funny easter egg)

What are the totally unsolved challenges? Granny3/Hush/CIFAR/Passphrase?

[severe pasture]

as far as we know yeah

[abstract rose]

So at least 3 (I don't believe much more) guys have solved Inversion

[severe pasture]

I believe it's at least 5

since 2 people not on 23 have claimed to have solved it

[twin wren]

how can u guys guess all the 6 parameters of mean and std in granny

[minor falcon]

Yep slightly more than 3 ppl have it

[rocky jacinth]

I think it just resigns when it knows it's losing rather than playing until checkmate.

[grave frigate]

I'm still at pickle😭

[ornate marsh]

samesies

[grave frigate]

🥲🥲🥲

There should be a hint by the team🥲

[ornate marsh]

most people seem to have gotten it. We just have to try harder 😄

[fervent obsidian]

I'm so stuck at Pickle that I think I have anger management issues now

[minor falcon]

This is a general good advice for most of the flags

[past brook]

pickle 🔥

[past brook]

man im in spot 101

😭

[fervent obsidian]

omg I got the Pickle!!!!!

I have tried things you people wouldn't believe...

[gaunt anchor]

I tried in pixelated things you wouldn't believe ... no flag ... but I feel I am just moving around it :/

[violet trellis]

I tried things you wouldn't believe in both of them, and got flag in neither...

[gaunt anchor]

hard work will pay off sooner or later (hopefully sooner for all of us )

I am focusing on hush now with a theory I am validating.

[violet trellis]

Nice. Good luck.

[gaunt anchor]

you too 🙂

[violet trellis]

tbh, this comment made me think that this problem is still more complicated than what I am trying lol

[fervent obsidian]

I wouldn't want to mislead you. it's just that among the ones I solved, this took me the most.

Many people already solved it.

[wind ether]

I think my biggest issue with inversion rn is trying to determine which set of letters/numbers to use (uppercase/lowercase, yes/no numbers, etc). It's annoying given that any attempt requires at least four hours of brute-forcing because of the three missing bits of info and every different set returns different results...

[minor falcon]

i'm far from having solve it despite all the time spent on it, but today i felt I put the finger on something new

[wind ether]

I hear that, I'll try and think about it differently. At this point I don't want to run another brute-force attempt until I'm reasonably confident about the five pieces of info we have

[minor falcon]

if it was pure brutforce, i think that by now, there would be more people having solved it 🙂

[jagged sluice]

that is a lot of bruteforce

127^8 attempts required

[minor falcon]

ez

[jagged sluice]

a casual 67675234241018881 attempts needed

surely aws can handle that kind of demand

surely right?

right?

[violet trellis]

Absolutely

[minor falcon]

if you work at openai, you can maybe borrow some ressources

[wind ether]

Somehow I feel it's either just lowercase or lowercase + numbers honestly, so only 2821109907456, seems doable

[jagged sluice]

67 quadrillion requests?

[jagged sluice]

nah surely the stopcodes are included :clueless:

[brave gyro]

hey everyone, i am new here. Till now, i solved 6 challenges. looking foward for solving more

[minor falcon]

welcome, good luck, and don't forget to eat and sleep

[jagged sluice]

hello new here, i am kenyeung

[minor falcon]

there should be a warning somewhere about the danger of solving a CTF without sleeping

[jagged sluice]

honestly this ctf should just adhere to defcon 3-2-1

or 6-3-2

[sand solstice]

I know it's irrational but I believe I am getting close to passphrase

[brave gyro]

Currently I am stuck at cluster-1. tried so many things but won't stop

[wind ether]

Also @olive ledge are we supposed to be able to batch requests to the inversion API? I always get 'Invalid input' with any size > 1. Would make my life much easier

[acoustic temple]

is there a single unique phrase for Semantle2 or possible more than 1 asnwer :?

[jagged sluice]

¯_(ツ)_/¯

[past brook]

... im going crazy

im starting to question if anyone has solved mnist

or if everyone is lying

its a conspiracy

[sand solstice]

do y'all have multiple notebooks open at any given time?

[severe pasture]

one kaggle, couple in google colab, lots of local ones

[minor falcon]

lots of kaggle, one local one

• a s3 bucket to pickle ( 🥸 ) my ongoing work

[brave gyro]

Yes solved, not conspiracy

[minor falcon]

the legends tell that the chosen one can solve MNIST and CIFAR with just an abacus

[sand solstice]

smart

can you pickle and resume entire notebook state? lol

[past brook]

but... the shapes dont make sense

https://tenor.com/view/controlmypc-cat-screaming-discord-gif-20582295

[gaunt anchor]

The shape of my eyes currently doesn't make sense .... need to sleep 😅

[plush carbon]

The most difficult part about MNIST is that it's really easy to overthink it. It is by far the least satisfactory flag I got. First, think what is a reasonable explanation of what is laid in front of you in the notebook (ofc, w/o overthinking it). Then, do some trial and error, and you get it.

[past brook]

i think ive tried every reasonable approach possible

without giving too much away, ive tried every scenario that fits into the two values in the input_data list

[plush carbon]

I was in the same rabbit hole, go back to the first things you tried. Usually for this question, the first few things you tried can lead you to the solution, not the ones out of desperation.

[jagged sluice]

inb4 next kaggle comp is predict which discord accounts are spam ones

[red tulip]

any clue for pixelated? I keep staring at those numbers in days 🥲

[devout pulsar]

{'negative': 0.3333, 'neutral': 0.3335, 'positive': 0.3332} still no flag ....

[gaunt anchor]

welcome to the club of 0.333 and no flag 😄

[nimble matrix]

How dangerous I need to be☠️

[hybrid crane]

name first 5 easy ones in there.. i'm sooo clulesss

[gaunt anchor]

I hate pixelated , I spent 2 hours trying to make the ocr work with the query then no flag :/ ....

[hybrid crane]

i'm starting to question myself at this point

I need a kickstart please🥲

[gaunt anchor]

check the discussions on the competition link on kaggle it should get you started

make sure to look around for resources here and on kaggle

good luck 🙂

[ornate marsh]

All great points by Ali! I would add that if you're just getting started, don't stick to one challenge, but try a different one if you get stuck.

🥺

[thorn quarry]

@brave briar any clues or suggestions or resources

[brave briar]

Basically I cannot give you any hint :). But for this specific one, things I found on this channel generally misled me. I also tried chatGPT, that also make me lose lot of energy. So I would advise for this one to just search by yourself.

and also, I advise you to try to solve it locally, not on kaggle notebook.

[glass bay]

what is the flag 1-6

[outer sundial]

https://tenor.com/view/oh-fuck-off-go-away-just-go-leave-me-alone-spicy-wings-gif-14523970

[ornate marsh]

I just solved pickle, I have no idea how, and I feel so empty 😄

or rather, i have no idea how it relates to the instructions

@amber glade Sorry to ping you on a Sunday, but just in case you hadn't seen this

[amber glade]

@ornate marsh how are you affiliated with this and why did you choose to pick me up among others

[ornate marsh]

I just saw you listed as a moderator in the side tab. I'm not affiliated with it, I was just reporting a scam. Sorry for bothering you

[amber glade]

Thanks for letting me know @ornate marsh

@ruby hearth Please refrain from posting such messages here, I will have to take this message down for now

@fading flare Please do not spam this channel with messages like the one you posted inviting people to join other Discord channels (Crypto related), I have taken down the message

[violet trellis]

I spent too much time on this problem with no flag. Given what people wrote here i just feel that this problem is too random to deserve a lot of time tbh. So, i think I'll focus on the other problems.

[gaunt anchor]

The hush server is slow ? anyone tried ?

[final path]

around 3 sec for test record.

[gaunt anchor]

hmmm

it took 37 secs to response for test :/

I checked from colab , kaggle .... best time I could get was around 22s response 😅 @olive ledge is the hush server still with us ?

[final path]

yeah, I checked, same 20+ for me now, yesterday I had like 2.5s avg for 2k+ requests

[gaunt anchor]

yesterday was fast ... I guess its time for hush to scale 🙂

[rocky jacinth]

Not solved it and feel like I have tried everything "simple".

[mild shale]

got many senteces with 0.33 0.33 0.33

never had a flag

[mild shale]

i did that the first so i didnt though much about other problem didnt overthing

[mild shale]

are you guys really have any hint what hush might be

[mild shale]

i dont really have still discovering and mining

[abstract rose]

For CIFAR, I'm wondering if sample input data provided in [125, 245, 0, 10000] is real data from expected computation we've to submit or random numbers just for example

[mild shale]

I think no
for the mnist problem, i checked the input data and it didnt match

[gaunt anchor]

I have an idea I want to test for hush , but the server response time is currently not so helpfull

[rocky jacinth]

I'm wondering the analogous thing for MNIST, but if it's just exemplar then it would be a stupid problem not a simple one

[rocky jacinth]

Not solved, but noted that "input_data is a clue".

[mild shale]

Its indeed a clue

[random minnow]

"For CIFAR, I'm wondering if sample input data provided in [125, 245, 0, 10000] is real data from expected computation we've to submit or random numbers just for example "
difinitely not a sample, but 10000 is also not a random number i think

"Come up with a difference sentence where everything is equivalent."
all score are 0.33, num of words =33, server runtime=33 msec

[mild shale]

i just keep giving '=' and didnt get flag as well

[devout pulsar]

did you reach 0.3333, 0.3333, 0.3333 ?

[random minnow]

I'm still stuck at cluster1 any help please?

[rocky jacinth]

No clues, but there is more than one way to solve either using the provided model or otherwise.

[bold ibex]

Asking for hint buddy

[rocky jacinth]

Competitors can't giving be giving spoiler hints.

[mild shale]

actually thats waht i did then , then after solving other i got to look and cluster 1 and understand what is was doing

[bold ibex]

I'm stuck on some other too 😂 like cifar

[rocky jacinth]

All of us are stuck somewhere.

@bold ibex

[bold ibex]

I'm asking for a hint not for a spoiler

[mild shale]

Solved?
if yes i can take 2 more days to solve it and i will also reach the 23 zone

[outer sundial]

Were you able to get Granny 3 in the local model ?

[minor falcon]

not solved yet, but getting frustratingly close

[sturdy gorge]

Did all the what the flags but 3, that childish response is driving me insane, cant seem tobypass it 😭

[minor falcon]

cannot answer about what i'm trying 🤐 but still stuck at 0.00069273, so i'm going to explore new horizons now

[amber totem]

For passphrase to me différence may be related to some mathematical logic

[vestal pawn]

any hints on WITF, have tried simple to difficult prompt, it says nothing useful

[hollow coyote]

Ya im lost if WITF 3+ lol. Just jumping around different problems and failing at each one

[sturdy gorge]

I had success on 4,5 with the same logic for 1 and 2

3 however.. not budging at all

[glass bay]

For witf there is a very helpful yt video that even links to a website with similar competitive tasks that teach you a lot. After watching them, i've cleared all the LLM tasks within an hour except IP and pickle. And the topic is very researched and researchable

Furthermore, clearing witf 1-3 with a single prompt

It is indeed interesting whether you can clear all from 1 to 6 with one prompt

I'd tell you what other techniques I used, but I won't because competition rules

https://tenor.com/view/random-bullshit-go-moon-knight-random-random-bullshit-gif-25725102

[minor falcon]

the one i found the hardest has been the pirate that talk about flags

[sturdy gorge]

that is a very helpful tip, will look into it, thanks!

[vestal pawn]

Can you share it??

[glass bay]

i doubt that

[final path]

this story reminds me of "Good Will Hunting" film

[median mauve]

Sleep is all you need!

[acoustic temple]

even harder than IP1 and 2?

[minor falcon]

according to my personal tastes

but it might differ from one person to another

[acoustic temple]

btw, is there any information what model is MobileNetV2 is ? it is Keras or torch?

I mean is it announced by host? or we should figure out by oursevles

[exotic mist]

for ip1 and 2, are the inputs dns records or prompts like wtf1-6?

[acoustic temple]

no idea, did not solve them yet, but it says: "We have a service where you can query it in natural language and find out where to send your traffic",

[outer sundial]

Need to figure out yourself.

[thorn quarry]

@minor falcon Yeah solved all witf with a single prompt but pirate is taking too much time how should I approach it. What's the difference between pirate and other witfs. After some days I started giving prompts in pirate accents even that didn't work...😪

Edit I got the pirate flag

[acoustic temple]

did you got IP1 and 2 ?

[thorn quarry]

I got IP1 after they modified the problem statement

[boreal spear]

solved granny2?

[outer sundial]

Yeah

[exotic mist]

are the inputs dns records or prompts injections like wtf1-6?

[devout jasper]

4 days on granny, can't still figure out anything...feeling really dumb

[orchid oriole]

figuring out expected input format is part of the challenge, if it's not clear from the problem statement

[final path]

i was like 5 or 6 days on granny, dont give up!

[devout jasper]

really difficult not to, I'll try

[rocky jacinth]

I think you have to experiment.

[exotic mist]

thanks, i just solved ip1

[gaunt anchor]

pixelated is teaching me a lot (really a lot) in the security world ! -- still no flag .... but much info gained

[dense lodge]

interesting I found pixalated quite easy even though I knew nothing about that stuff.... but mnist 🤯

[gaunt anchor]

hhhhh I have the opposite answer completely

[dense lodge]

but pixalated gives you some feedback, mnist is either you get it or not there's no progression

ok just solved mnist

LOL

kind of hate myself as I had this idea but didn't bother to try and now I fell outside of the bronze band .......

[devout jasper]

you may want to cancel this comment

[dense lodge]

how hard did you guys find sloth?

[past brook]

I have a very logical assumption of what I should do in the task

given the values

BUT

the output shape doesnt fit

[past brook]

has it been solved?

[craggy beacon]

yep

[dense lodge]

I pretty much just found the staticflag, just need to read it 😅

[naive umbra]

Working all day on sloth because I thought it would be easy but no luck. Went back to MNIST to try 1 thing and finally got the flag 😅

[past brook]

ive been on mnist and cifar for 3 days+

[buoyant frigate]

is hush server down?

[limber flower]

Checking now

[brave briar]

granny is also slow. It used to be faster. It was the same last week end and during work days, servers are more available 😀.

[gaunt anchor]

The hush server is down or very slow its been so most of the time today ( like 12 hours so far 😅)

I can’t really test

[limber flower]

Working on it now

[gaunt anchor]

Great thanks 😊

[dense lodge]

huh took me an hour, back to bronze

[gaunt anchor]

You solved inversion ?

[dense lodge]

nah haven't tried that

[gaunt anchor]

Ah static you mean the sloth

[limber flower]

Services should be back up and re-scaling.

[gaunt anchor]

My bad 🙂 , once I see the word static I go inversioooon ! ....

[sturdy gorge]

almost 6h in what is the flag 3, this one is not budging 😔

even pirate only took 3 prompts, by witf3 still wont budge

[empty bane]

you'll get it 🙂

[minor falcon]

looks like your prediction was wrong :p

[glass bay]

not a bad thing to be wrong about

[minor falcon]

depends for who 😭

[gaunt anchor]

Still stuck on pixelated … I tried everything I found or learned about and I know why it’s not working …. I am overthinking 🙄🙄

[granite goblet]

for the mnist problem, is the second part of the input data really not relevant??

[glass bay]

try it either way

[nimble matrix]

How dangerous I need to be to get the flag😔

[glass bay]

you need to be perfectly dangerous

[versed jungle]

many have claimed they could solved MNIST without making sense of the 23435 ... which looks magical to me !!

[jagged sluice]

there are 23435 possible solutions

[sturdy gorge]

Ip1 and 2 done, still no witf3, going insane

[upper merlin]

is 403 errors (I guess because of too many calls) shared between different questions? e.g. will I get 403 more often if I do a lot of calls to granny and pixelated at the same time compared to if I only do granny or pixelated?

[minor falcon]

when i trigger the 403 i wait 3min and regen the request, that works fine so far

[upper merlin]

Yeah have kinda same workaround, just seemed to trigger more often when I started my other stuff on the other questions simultaneously, but might just have been a coincidence

[past brook]

https://tenor.com/view/im-sorry-what-calvin-payne-house-of-payne-what-did-you-say-can-you-repeat-that-gif-24039762

[sturdy gorge]

Is semantle2 possible without bruteforcing?

possible or, has it been done like that so far?

[glass bay]

i believe i've won

[wind ether]

I didn't brute-force it, but it would've definitely been easier if I did

[sand solstice]

like many questions, it was a combination of both; either I start with bruteforcing and use intuition for the rest, or I start with a hunch and exhaust the options

[hollow coyote]

Got them (minus #3) with a single prompt. Will be fun to look over and share these after the competition ends

[amber sage]

so your solution does need the magic number 23435?

count could mean say number one after another or calculate total number of sth. tried a number of ideas, none worked.

[wind ether]

I don't get how people have solved inversion easily, there must be a "best" way to do it to get everything to line up and it's definitely not traditional model inversion

[olive ledge]

LLMs are like that.

[olive ledge]

I think it has to do with the datasets you happen to use.

[acoustic temple]

I am also banging my head against MNIST... I've found a few different ways to arrive at 23435 each of which could arguably be the solution, none of them seem to be 🤔

[wind ether]

Hmm, I'll rethink my strategy. Also was wondering re my question earlier--is batching supposed to be allowed for the endpoint? Every time I restart my notebook I need to send another 1000-10000 requests to build the train/test set for my model. Would be much easier to just do it once/a few times. (Guess I could just save the output actually)

[waxen lynx]

finally got MNIST after 8 days of ovethinking 🙂

[olive ledge]

You technically don’t need a notebook…

We’re discussing making some changes. They’ll be announced well ahead of time - but it’s a competition so we’re generally on the “no changes” train.

I’d rather people are mad at us for a misguided implementation, rather than causing someone to lose a spot.

[wind ether]

Makes sense, honestly I don't think that changes really need to be made, maybe a few things could be made more clear, especially with Passphrase (as I think the main difficulty is actually figuring out what to do), but by-and-large the competition has been great thus far (as long as granny3 is solveable 🙏 )

[gaunt anchor]

No one like to lose a spot 😅

[exotic mist]

nice, solved these three yesterday, same prompt worked for me for ip1 and 1p2 😄

[random minnow]

i am still stuck at pickle ... i wonder:

1. if my payload is well concealed, it will not be detectd and will be unpickled.
2. if my payload is detected, it will not be unpickled.

Or there is no unpickling at the server at all???

[sturdy gorge]

Exactly the same issue here, 3 won't budge at all

[glass bay]

too much info, won't say

you can assume both and go with your assumption

[gaunt anchor]

@random minnow I must say I enjoy every thread and discussion you are involved in, A researcher by heart ! 🫡

[tepid zenith]

not sure if it is okay to ask or not, but can someone clarify if inversion static flag makes sense? stuck on it trying to make sense of output since last 3 days

[violet trellis]

I didn't solve it by far, but tbh i suspect it's a LLM problem but can't find evidence for that.

[wind ether]

I'm pretty confident that it should make sense but not 100% sure. Also not sure if it's a word or phrase

[wanton patrol]

I also think this information should not be given to us. The fact that it was possible to solve Inversion without having that piece is enough for me.

aka it would be unfair to the people who solved it this far

btw, knowing that something is solved is also information
f.e. if some search space is obviously too large for someone to just get lucky while brute-forcing, you know there has to be a "trick" they applied, some extra knowledge/method etc
and knowing what is "obviously too large" is part of the skills one should have to do well here

....say I while trying to brute-force Granny 1 🤣

[versed jungle]

I wish I had a solution ... but I didn't manage to understand the clue yet

[real kindle]

who have scored above 10/12, how many days you guys devoted on an average?

[glass bay]

got around 8-9 in 1 day, 12-13 on the second one

mostly on LLM things because they are rather formulaic and similar in the approach

[wind ether]

Yeah agreed, LLMs, Cluster1-3, Semantle1 go fast and that's 15 right there. However for reference I've spent around a week on Inversion. It and Grannys have taken up most of my time thus far.

[craggy beacon]

moohax — 15.10.2023 20:18
There is no actual code execution.

[random minnow]

oh

[past brook]

let people work the task out by themselves

imo youre giving to much away

[minor falcon]

i'm giving up on inversion for now i ran out of ideas, and even if i thought i figured out the magic, apparently not 😢

[glass bay]

That's where the social engineering part comes in

[tepid zenith]

How much, it’s time 😭

[glass bay]

Alright
I will hint you
The hint is: reread the flag prompt

[minor falcon]

please don't make me go back to this nightmare aha

[glass bay]

Like honestly, looking back, it might be helpful to try interpret the prompt in some way

Except what I can reassure you of is that Q in Ouija is accidental and does not hint to anything (atleast within this flag)

[minor falcon]

making progress on your remaining tasks you ?

[glass bay]

Nope, was resting on the weekends, although I have had a few thoughts on some of them and may try them later

[ornate marsh]

is it official that the Q is accidental? 😄

[glass bay]

nope. Like i said, social engineering is a part of the competition

...and now you'll doubt, whether you should believe me or not

[ornate marsh]

you're playing 7D-chess, I'm struggling with hungry hungry hippos 😄

[final path]

It is official, actually.

[minor falcon]

french version, which is also with a "O" according to that same discussion 😅

[amber sapphire]

Nope, MNIST and inversion are driving me crazy 😩

[minor falcon]

mnist is manageable, especially with all that has been said in this discord

[amber sapphire]

I will re-read everything, sure there's something I'm missing

[amber sage]

maybe counting mnist needs label

[exotic mist]

did you send your kindest wishes or warmest regards?

[fervent obsidian]

is it weird that I was able to solve Granny 1 but not Granny 2?

[fervent obsidian]

Literal skill issue, lol

[minor falcon]

🤷

[boreal spear]

the inversion competition🤔

[minor falcon]

i'll be so pissed when i'll see the solution revealed and discover i was off one character 🥺

[minor falcon]

ah, a new guy has got to 23, congrats to him

new ticket for itm going closer and closer to 24 flags

[final path]

i spent one more day to solve granny2 after granny1, so it's ok

[minor falcon]

making progress Mikhail on the golden square (the 4 apparently unsolved challenges*)

[devout jasper]

at least you solved one

[final path]

not much yet, researching hush, tried some ideas on passphrase but execution is hard and given vague prompt it's probably not worth it.
my new ideas for cifar immediately fall to "way too overthought" category.
granny3 is ☠️

[minor falcon]

yeah CIFAR everytime i find an idea that would fit in the "not too overthought" i end up with the same rewarding message "try again"

i'm wondering which one will be the first of the 4 to fall the first

[final path]

I took me literally 2 queries for MNIST, but CIFAR is something completely different. Maybe someone from club 23 solved CIFAR, we cant be 100% sure that's these are the same 23 as mine.

[minor falcon]

yeah maybe

cifar is really vague, but the fact that it is so vague is maybe also a strong clue

[wind ether]

I haven't looked at hush at all because audio data is intimidating but I at least have approaches that I want to look at for the other three. I think at least CIFAR and passphrase will be solved by the end of comp

[minor falcon]

yeah me i keep the hush for after inversion. If im not able to solve one, i don't see myself going to the other

passphrase, i'm not sure someone will be able to solve it because

• its wether a trick question and we are all missing the subtility
• there is a bit of brutforcing (or at least smart searching) involved, and the indication is too vague so its hard to see if we are heading toward the good interpretation.

i'll bet more on CIFAR/Granny3 to be solved, at least thats where i'm currently putting my efforts

[acoustic temple]

regarding passphrase is there a guaranty that if we got:
0.3333, 0.3333, 0.3333
it will give us flag?

[minor falcon]

nope, thats what i'm saying, nobody knows what is exactly the objective, and there is many way of interepreting the message given (without making a list here as it would give too much info i guess)

[wind ether]

I think we might get a hint if it stays unsolved for much longer just because the difficulty is in figuring out what we need to do. I'm at the point where I can influence pretty much any three pos/neg/neu values to 3 sigfigs but it's all a moot point if there's a single solution or something

[empty bane]

i definitely prefer the challenges where they're harder but you at least know what your goal is (more like semantle 2)

or sloth even i think that one was reasonable

[wind ether]

I'm leaning towards the passphrase solution to be semantle3 though, noticing some weird trends

[minor falcon]

might be also granny - related. Maybe a certain score is to be reached under certain circumstences, and the flag would not trigger overwise

[final path]

In chat you can find examples with 0.3333 all and no flag. And given that "both example input and output are important", that is probably not the way.

this is one hint about passphrase

[acoustic temple]

hmmm, I did see scores like up to third decimal point, but not exactly 0.3333, thats why I mentioned that, maybe the goal is to be super precise!

[minor falcon]

there were 100% perfect score posted, indeed

[acoustic temple]

oh btw, did you got passphrase ?

[minor falcon]

like there was also almost perfect score posted for granny

[minor falcon]

ah didnt see that one, interesting.

[final path]

and that the second. but maybe it's not about Passphrase 😄

[final path]

afaik passphrase is unsolved

[minor falcon]

going toward the granny observation. We are maybe all trying to submit a picture of an apple while we should be slightly more subtle

[gusty warren]

For Iversion, the prompt says "It's basically an AI Quija board.". Is is supposed to be "Ouija" board? Cant' find anythign about Quija board

[minor falcon]

yep thats a typo, it has been clarified by the organizer

[gusty warren]

Thank you!

[final path]

@empty bane how is your progress? still struggling with inversion or trying other stuff?

[empty bane]

Inversion mostly. But I've sort of run out of ideas, lost a lot of steam

[wind ether]

Wow, first 24 solved on LB!

[gusty warren]

Trying to tackle Inversion, Is "static flag" as in Inversion also a concept used in last year's competition? I am guessing the static flag to be a 8 char string, but I am begining to question myself.

[outer sundial]

Who is Bingus Traveller The love doctor

[minor falcon]

thats ashame this person is not here on discord, would be curious to know which flag felt

but at the same time the fact that other people dont know is certainly a hedge for him

[boreal spear]

it's moohax

🤣

[empty bane]

i was thinking that, trying to spur us on

[final path]

Maybe it's the main reason he got 24 first 🙂 unbiased ideas and more time w/o shitposting xd

[empty bane]

but no, they participated in a norweigan university internal competition 2 years ago 👀

[minor falcon]

without shitposting, i'd have abandonned for a long time personnally aha

[wind ether]

I think it's definitely CIFAR that he solved, I really doubt any of the other three

[minor falcon]

i think the most managable currently its granny 3

the guy maybe got hush

[mild shale]

@olive ledge can we get the statistics of how many solved each problem

[minor falcon]

even if I wish we could have them, i think its a bad idea, it would penalize the people that are alone having solved a particular problem

like if i'm the only one solving granny3, i will certainly not tell it, fearing I lead everybody to focus on that one knowing its more managable than another

[olive ledge]

^

We’ll release hints and stats post competition.

[random minnow]

why i end up with teapot?

[gusty warren]

according to this rank, sloth is ranked as easy as IP1,2 and Cluster1,3. Does this makes sense?... Saw someone spent days on sloth...

[acoustic temple]

it starts with "based on my experience", so it depends on person,
myself I found Semantle2 is much easier thanCluster1, which I'm stuck in now

[sturdy gorge]

Probably a very personal ranking, i got IPs within minutes, and have 5h+ of cluster1 without any flag

[brave briar]

We all have kind of nemesis which seems easy to others 😀 . Due to skill ? luck ? overthinking ?? Don't know. It can be MNIST, sloth, granny, pixelated, WTF3 or pickle depending on each one.

[craggy beacon]

Are you professional semantle player?

[gusty warren]

Right, I see....... for me, almost all problems with directional feedback are quite easy

[waxen lynx]

Don't give up, it took me 2 days to get 19 flags, then I went stuck in MNIST for 8 days in a row due overthinking 🤯 . Now in a couple of hours got Granny1&2.

[gusty warren]

The ones without clear directional feedback are just so frustrating...

[acoustic temple]

hmm no can't say it

[hollow coyote]

At 13 flags!

[median mauve]

This is when you are too good at Kaggling 😄

[amber totem]

passphrase is just hard to understand, doing analogies that we are supposed to do make things even more difficult haha

[glass bay]

god i hate pixelated

the task itself is awesome but the OCR makes me wanna pull hair off of my head

[minor falcon]

I propose each person to get a joker to use for one of the task 😀

[glass bay]

how sometimes letters just disappear

[minor falcon]

actually i did not find the OCR to be so bad

i struggeled a lot with a particular character, but it turned out i did not need it...

[glass bay]

its like 95% about the font and the way you alter your picture and submit it

[amber totem]

don't overthink, great ressources for this one in the conversation. I got stuck too but it helped

[boreal spear]

old london is all you need

[glass bay]

but even after excluding the font and minimizing other factors i still change 1 pixel to 254 254 254 and the whole 100 character query goes wild

[outer sundial]

I don't even know which font i used

[minor falcon]

for the reference, old london is one of the first font i tryied for inversion 😭

[tepid zenith]

old london is legendary

[glass bay]

funnily enough i did find them which SEVERELY helped with the consistency

[boreal spear]

or something like Gothic

[minor falcon]

you should try different approaches to generate texts

(worth for all the people stuck with OCR)

[glass bay]

but still i've spend 2 hours failing to make ocr recognize one last mislabeled character correctly

like i'm pretty sure that like a few more alterations and i'll manage to make it but still that is really maddening

[glass bay]

out of like (idk if that number is too much of a hint) 50+

[glass bay]

yeaaaaa i was certain that Paint, despite helping me with some other flags, may not be the best tool for the task

[brave briar]

guys you are saying too much ! I know it s hard 😀

[amber totem]

if you are talking about passphrase we are only relying what moderators told us 🙂

[brave briar]

no sorry my first message was a mistaken reply, I was talking about OCR talk

[amber totem]

oh np

[median mauve]

let's switch to granny hints 😄

[devout jasper]

[boreal spear]

let's share inversion hints

let's share notebooks

it's a joke common guys

shared mine, and yours?

[glass bay]

alright actual inversion hint
the flag message does not contain unprintable symbols like \n \r \b \a \0 etc.

[empty bane]

inversion hint: the flag is the name of the last person who solved inversion

[minor falcon]

i give you a nice one liner for inversion:
while True:query("".join(list(np.random.choice(list("abcd...."), 8))))

[amber totem]

Am i the only one who is receiving primate messages from anonymous accounts to share hints ?

[severe pasture]

I haven't been asked to share hints yet... feels bad

[empty bane]

few people have mentioned that, i havent received them myself

but also if they're in this server then they're not anonymous

[outer sundial]

My count is 4, 1 is even active sometimes in this chat.

[glass bay]

3

[minor falcon]

i got one guy that tried two times, i threat him to talk to orgs, he stopped.

[amber totem]

3 too

but didnt answer

[minor falcon]

you can create a new kaggle account/new discord account, and you are anonymous again

[mild shale]

No one asked me 😢

[minor falcon]

you are not shitposting enough

[amber totem]

well now you can be sure somebody's gonna ask you haha

[empty bane]

that's true, most cheaters don't think it through tho

if they could bypass anticheat they could solve some flags

[minor falcon]

am I the only one ending up with 100 notebooks starting like notebookxxxxx or ctfxxxx and not able to find something when i need it ?

[outer sundial]

I have 30 notebooks for granny

[amber totem]

only in my terminal

[glass bay]

just 3 for me

[mild shale]

I have only 3

[gaunt anchor]

my all Untitled notebooks on colab are related to this 🙂 ... now its Untitled47

I am to lazy to name it :/

[mild shale]

But once the interactive mode was alive for 27 hours 😪

[gaunt anchor]

oh one thing .. if the UntitledX with a flag , its named UntitledX_yes 😄

[amber totem]

i only have one notebook and i delete ctf parts that i've already solved

[tepid zenith]

I just quick save them and delete that particular problem from the notebook. Gives a big relief ☺️

[amber totem]

yeah exactly same

[glass bay]

afaik for top5 you need a notebook with solutions and a write-up so i'm not deleting none of my cells

[gusty warren]

Lol... just got the joke, I am also sadly getting a teapot

[brave briar]

if someone asks you in private for some hint, give him a very bad clue that will give him no chance to find it out 😁 .

[random minnow]

teapot and coffee?

[gusty warren]

Now I am confused whether the teapot is a standard implementation/joke or actual hint..

[severe pasture]

yeah my inversion folder is starting to get depressing

[gaunt anchor]

what I am inserting to pixelated makes perfect sense! yet no flag! I started to like the sloth because of pixelated 😦

omg ! I did it pixelated done !

stupid silly OCR

22 flags finally 😄

[sturdy gorge]

Are there any predictions on how many will be needed for bronze in the end?

I think we finished it at the same time, I was about to come here and vent a bit about it but my solution worked 😄 Congrats bro 🔥

Trying to solve Inversion/Granny 3, valley of despair it is.

[sturdy gorge]

Does the order of the words matter in semantle2? 🤔
Edit: does not seem it does

[gaunt anchor]

I am already working and focusing on inversion (8 or 9 days so far) and hush ( 7 days I think) ... so I know the feeling , but pixelated was the one that drove me crazy because I know I had it !

[abstract rose]

For inversion, the AI want us to guess 457 as it never learns about it or it's another secret to figure out?

[gusty warren]

Are there consensus yet whether pickle is an LLM?

[jagged sluice]

yes

[minor falcon]

i think the answer to this question would give a free flag to 99% of the people stuck 😅

[dense lodge]

It definitely matters for a random sentence, unclear if it matters for the solution

[gusty warren]

And the consensus is that it is ineed an LLM?

[jagged sluice]

¯_(ツ)_/¯

[minor falcon]

currently the consensus is focussed on other tasks 😭

[past brook]

dude im gonna spend the rest of the competition on mnist i swear to god

[minor falcon]

ok i'll give you a hint to solve mnist you need to

ah wait someone is ringing at my door...

[outer sundial]

Is it moohax ?

[past brook]

https://tenor.com/view/hey-there-peep-hole-surprise-ben-chang-ken-jeong-gif-15442336

[past brook]

hmm, i didnt have the same experience

i didnt feel like the ocr was that bad I got a hang of it

[sturdy gorge]

Interesting, dont have the answer yet, but ran like 4/5 tests on some words and it provided the same score 🤔

[sturdy gorge]

thats interesting

[dense lodge]

got semantle2, I guess I need to turn my attention to granny now

[craggy beacon]

your thoughts on semantle 2, like it? i stuck at 0.98

[sturdy gorge]

Im at 0.89 on sem2 🥲 so close, yet so far

[dense lodge]

I guess just keep going I didn't do anything smart at all

[dense lodge]

you solved granny 1 and 2 then?

[craggy beacon]

yep, they are actually not that hard

[dense lodge]

hopefully 😅

[sturdy gorge]

oop, one of the 4 problems fell

Bingus is at 24 problems on the leaderboard

[gusty warren]

Pickle is so frustrating.... Many suggested to read the prompt.. "This is not the code execution you are looking for...waves keyboard" yet there are just so many possible interpretations...

Is the pickle flag static?... Feeling like I am playing hide and seek with the notebook.... Or is that a waste of time...

[devout jasper]

well well

[gaunt anchor]

another 23 on the board , now the goal is 24

its going to be a long 17 days

[abstract rose]

I've a few (different) perfect matches but it goes nowhere to me

[minor falcon]

yeah i'm at the same point, i also thought i figure out more, but it still leading nowhere

[nimble matrix]

finally got the sloth but can not get over the pickle

[abstract rose]

F1 score of the underlying model might be quite bad 🙂

[minor falcon]

the bad part is that some characters can be easily swapped between upper/lower case, so its multiplying the search space if once want to include everything

[sturdy gorge]

there is a 24 on the board already 🙂

[gaunt anchor]

Ya I know , I meant that 23 now is not enough 😉

[sturdy gorge]

ahh dam, best of luck those going for gold haha

[devout jasper]

still trying to match my local vs api model

23 is a mirage

[hard perch]

Stuck with MNIST. Really confused if it’s related to the actual dataset. Seems like the tensorflow one and others aren’t same. Which one to use?

[jagged sluice]

¯_(ツ)_/¯

[viral bough]

i'm getting tired of 'I know you are, but what am I?'

[brave briar]

humans generally get tired before machines 🙃 . Take a break and fight him again ! Definitely the hardest of the 6 to me !

[jagged sluice]

I know you are, but what am I?

[past brook]

tensorflow is same as pytorch

atleast from what ive seen

but ye i am also stuck on mnist

[glass bay]

tfw a prompt for witf 1 accidentally worked for witf 2 and 3 and you don't even know their gimmicks

[sand solstice]

no one has solved granny3, hush, and passphrase afawk still?

[sturdy gorge]

oh, so the one that fell today was cifar?

[sand solstice]

cifar is still unsolved too

blocked it out of memory lol

[empty bane]

someone has 24 now so one of the 4 is solved

[ember relic]

then theres me who solved 4 witfs with the same prompt 😂

[sturdy gorge]

yeah exactly, lots of silence here regarding that haha

people hiding the one that fell 👀

[minor falcon]

nobody knows here i'm afraid, we are all busy figuring out our own troubles

[sturdy gorge]

fair fair, jsut really curious

[nimble matrix]

I have got all 6 😂

[past brook]

https://tenor.com/view/stewie-griffin-family-guy-mental-gif-25999400

doNt oVErThiNK iT

[sand solstice]

starts overthinking

[minor falcon]

arf, i thought i had the illumination. Found a match that would fit almost perfectly with all my findings... but nope.

[sand solstice]

many such cases

[ember relic]

wait so i dont understand

are some datasets incorrect for mnist?

[glass bay]

You can search over this channel to find a hint about datasets to use in mnist

[devout jasper]

I'm giving up on granny...can't match the models 😔

[sturdy gorge]

having trouble understanding what kind of output format we are suposed to feed to granny

[sand solstice]

Look at the starter notebook

[ember relic]

ok just got mnist and i can say i totally didnt get the input data clue

[lyric token]

brute force?

[ember relic]

nope

just boggled my mind

i always thought of something different

[gusty warren]

You mean the two numbers in the input_data is not needed at all?

[jagged sluice]

¯_(ツ)_/¯

[ember relic]

im saying that i misunderstood the clue

[gusty warren]

okay.... yeh, we all do until the aha moment.

[olive ledge]

Some people did it this way - you don't need to do this. In our solution for testing, we don't use a surrogate model.

[nimble matrix]

in pickle, do we seriously need to be dangerous or it's just another LLM?

[gusty warren]

sharing your pain...

dang.. just got sloth. One of my favourite so far, one that you can do with pure reasoning and not guessing/word play

[nimble matrix]

sloth seemed too easy compared to the last time

[gusty warren]

Yeh, multiple clues manifest itself and point to the same direction, no guessing involved, just so straight forward compared to others..

[nimble matrix]

I am crying because people are saying same thing about MNIST as well and I am nowhere near

[gusty warren]

same here. The input shape looks like dead giveaway and stragith forward, except no flag

switching to granny 1, seems doable. but I heard people having perfect score but no flag? I thought I was just supposed to upload an apple, apparently it didn't work

[thorn quarry]

So you are saying that I won't get flag even if I reach 1.0 for granny ?

[gusty warren]

I missed the word "almost", #ai-village-capture-the-flag-defcon31 message

Or maybe I was misreading the context

But seriously I don't understand the goal, my first thought is to get a socre higher than any other class would be fine (come on! it is level 1!), I was terribly wrong..

[thorn quarry]

Yeah I did the same I also tried to keep the timber in the second place and granny in the first that didn't work too..

[gusty warren]

Lol, I did that too, try to keep the wolf around, and still no flag

The other hypothesis (which I didn't try) is to put the wolf at the bottom, but that would make no sense...

[thorn quarry]

It's possible to do that I'll give it a try once

Also why did they name misclassifications question as cluster 1. I thought it will be easier than 2 n 3 as I solved both in 20 mins. I don't know what to do ? Any resources to learn about it?

[gusty warren]

cluster 1? Just look at the data, and do real data analysis. Straight forward, no word play. If stuck, just try and let the feedback guide you.

But you are right about the ranking, cluster 2 is a joke to me...

[thorn quarry]

I've heard in the chat somewhere that you can get the flag for cluster1 without using model,
Is it true?

[gusty warren]

I think that's true for multiple flags.....

[glass bay]

Well, maybe. Try it

[topaz ember]

Well, MobileNet-v2 mentioned in the prompt scores ~85% timber wolf for the pic provided, and not ~28% returned by the query. So the model/prep is obviously different and people are trying to match 🙂

[gusty warren]

Are there any good tools to convert text to img?.... Using MS paint is not working well...

[lyric token]

Python?

[gusty warren]

Good suggestion, when I searched text to imgage, I got all Generative AI results.. Need to work on my google skill

[fallow vault]

stucked in cluster3 more than a week. response messages for the same input is constantly varying alphanumeric string of length 21. is there any meaning? or just by chance?

[thorn quarry]

Sometimes you have to just stare at what you are getting

[fallow vault]

ok seems a different angle, think about it doing semantle2

[gusty warren]

OCR really sucks.... funny that there is a font called OCR and it is terrible at being recognized

[gusty warren]

Chatgpt told me that the response I got is typically an indication of successful insertion. Yet not flag, sigh....

[real kindle]

waste 6 hrs in IP

[gusty warren]

I am sure there will be memes about IP1 and IP2. I got the two flags and I still have no idea how...

[real kindle]

I have no clue now on IP.

[gusty warren]

You just need to try, and at least you know your input are being processed properly when doing the IP. The OCR for pixelated is just wasting time

[real kindle]

yeah.

[random minnow]

one whole list of papers: https://github.com/stratosphereips/awesome-ml-privacy-attacks

[robust talon]

how do I interpret the score in cluster 1? do I maximise it to get the flag or minimize it?

[gusty warren]

Make hypothesis, and then test. This one should not be hard to test.

[twin wren]

in granny, the local model can only match the server up to 7digit

is it a match?

or i need the exact number

[boreal spear]

another 24

[minor falcon]

cool it will be time soon to give up and be free :p

[sturdy gorge]

pickle is really testing my anger control at this point 🥲

[orchid oriole]

same. lastly found some inconsistent behavior which I deem too random to be part of the chall but which makes me question WHAT EVEN EXACTLY IS THE CHALL.
Thought it had a very straightforward goal and I just had to try hard enough, not so sure anymore

[worldly zinc]

same. cluster 3, pickle and pixelated really confused me because I think I found many clues in all three of them, but I tried for days and couldn't get the flag. sad...

[median mauve]

even for granny 3?

[sturdy gorge]

I dont think i have any clue at all for pickle, reading on base 64 and serialization, some ideas come to mind but nothing seems to work

[random minnow]

i wake up and sudden;y solved pickel????
just reoragnize my code and reimplement old initial ideas

wasted one week

[sturdy gorge]

congrats! 🙂

[boreal spear]

Now it's inversion time

[random minnow]

the two most solvable ones in my opinon are inversion aand passphrase

both are model inversion which can be done

for passpharse, i am worling towrads this hint "The sentiment about this sauce became so powerful that it was encapsulated into an AI model."

[sturdy gorge]

isnt passphrase one of those that ahs not been solved yet?

[fallow cargo]

Which are the problems still unsolved?

[craggy beacon]

there is a chance that everything is solved

[glass bay]

4 days later, pixelated's ocr recognizes my text correctly. the issue is that query is way off :/

[boreal spear]

many people got 23 today

what tip

[outer sundial]

3 people in last 30 minutes 🤔

[craggy beacon]

yep also there is sharing behind the scene

[boreal spear]

🤔

[ornate marsh]

https://tenor.com/view/йокелемене-men-in-black-light-sunglasses-gif-15516530

[outer sundial]

I am not making any speculation.

[boreal spear]

I only care about the tip🤣

[amber totem]

Hm

[outer sundial]

But i hope there is no tip.

[craggy beacon]

ahaha

[craggy beacon]

just good old team work

[outer sundial]

AHEM

[boreal spear]

hackers sometimes collaborate🤣

[outer sundial]

1 more guy to 23 from Italy

[craggy beacon]

teaming with people you knew and sending flags almost at the same time 🤣

[lost relic]

I guess they don't know collaboration is not allowed

[glass bay]

@olive ledge ^

[craggy beacon]

if they send the same tasks at the same time

when it is obvious teaming

[glass bay]

99% sure they've waited for top5 to fill up to not do write-ups later

[boreal spear]

23 is not enough for top5 imo

[sturdy gorge]

gold medal farming

[final path]

i think even my first 23 won't be enough for gold..

[minor falcon]

Im geniully naive but i think people would not risk to cheat, especially at that high level, and without any subtility. I'll vouch for coincidence here

[gaunt anchor]

The speed 23 is appearing is crazy 🙄🙄🙄🙄

[sturdy gorge]

Btw, this is my first active kaggle comp, do people below bronze get any points or something? or is it just bronze+?

[minor falcon]

You get a chocolate medal

[boreal spear]

you'll get a granny smith apple

[wind ether]

Idk I'm a little suspicious, given how few people have solved inversion, that they seem to know each other, and they all got it within a very short timeframe

[gaunt anchor]

I can only think of inversion static key is shared somehow maybe !

[sturdy gorge]

mnhhh chocolate medal

[craggy beacon]

same but they were in the same team before

[outer sundial]

Time to search in Italian socail media ?

[sturdy gorge]

Italian kaggle twitter scrapping

[craggy beacon]

maybe this is some kind of a clue🧐

[brave briar]

When I see the italian team submitting all at the time with so little discretion, I really wonder why to bother to respect rules...

[craggy beacon]

Maybe guy at the first place is actually a team of students somewhere
10k$+ is not a bad sum

[wind ether]

I don't think it's worth worrying about right now--we should give them the benefit of the doubt and trust the moderators to investigate as necessary. Lets get back to solving the challenges

[brave briar]

I could have let the benefit of doubt for 2 challengers indeed, but 4 ... Come on !

[wind ether]

I mean if they're cheating, it's obvious enough that I'm sure they'll be removed. No point speculating tho

[minor falcon]

Lets go back to shitpost* solving puzzle takes too long and too much energy

[ornate marsh]

where are y'all stuck right now? I'm jumping between MNIST and cluster1 :/

[boreal spear]

But they did solve inversion, that's strong

[wind ether]

Still inversion, life is pain

[wanton patrol]

wait, how do you know that?

[brave briar]

trying inversion, but seems I have difficulties to interpret spirits

[gaunt anchor]

I hope there is no cheating , a gold or silver medal is important for me … to push my way to master 😅

[boreal spear]

do you think they solved hush granny3 cifar or passphrase?

[ornate marsh]

Inversion tip: you can only solve it at night during a thunderstorm

[wanton patrol]

I don't know 😄 could be any, but yes, inversion is the most likely probably, I just thought that maybe they had changed their team names or something 😛

[brave briar]

yeah all four named "solved cifar" 😉

[naive umbra]

I got mnist but I'm running blank on sloth..

[wanton patrol]

LMAO, after lecturing here yesterday about the importance of error checking and logging in your scripts, it turns out I had not done it properly for my Granny 1 notebook and I lost my flag 😅
luckily got there again after fixing and rerunning it....

[devout jasper]

well, I'm italian but I was not invited to the party

[wanton patrol]

There is another Jacopo in that team, it seems 😛

[devout jasper]

so not even having the same name was enough...

[outer sundial]

It would be too obvious if two people with same name reached 23 together.

[brave briar]

try submit your name to passphrase

[devout jasper]

I guess the minimum requirement was to have granny 1 and 2 solved but I'm too dumb

[devout jasper]

I did in pixelated, I got "you are not invited"

Bingus Traveller is another italian for sure.."love doctor", come on

[amber totem]

moderators may have every log to check if they suspect cheating

[brave briar]

they are all competing to another competition : NeurIPS 2023 and have teamed up on a previous competition : RSNA Screening Mammography Breast Cancer Detection.

[outer sundial]

You are right, I just went through profile of all 5 of them and all are competing in Defcon and NeurIPS individually.

[brave briar]

But more generally, I wonder if this competition would not be even more interesting if team were allowed. Competing 1 month without discussing concretely of the problem is so hard.

[minor falcon]

Team is not a good idea here because you can split the tasks

[devout jasper]

what's even more funny...they are colleagues

at Leonardo

[amber totem]

if teaming was allowed problems would be 3 times more difficult

[orchid oriole]

dayum got pickle

[orchid oriole]

agreed, CTFs are just so much more fun with a team.
More social, less being stuck.

Maybe make the competition only half as long but allow teams next time

[final path]

when you did something wrong in front of CTF hackers and in 5 minutes they know who you are, where you live and even your cat name 🙂

[olive ledge]

Noted - thanks for the heads up. Will get this to Kaggle and we’ll investigate.

[acoustic temple]

same, cluster 1 seems easy and still not sucess

[ornate marsh]

indeed. Can't wait to see what I was missing 😄 Same for MNIST

[fresh sorrel]

This is my first ever CTF and I'm stuck on Cluster Level 1

[brave briar]

it is not evident but difficulty is not in order. Have you tried cluster 2 ? It may inspire you for cluster 1 😀

[fallow cargo]

We are doing the challenge.... i can share my solution with the organizer if there are any problem @olive ledge

the other can do the same

i don't have nothing to hide

I think the organizer have the submission time and statistics and they can also check that

[fallow cargo]

Sorry but ask for our solution if there are issues...

i can give mine immediatly if you need it

After that ill stop immediately the challenge if tehre are problems

[craggy beacon]

if it is not a secret what flag did u send last

[fallow cargo]

well first i want to understand from the organizer

what i did

[craggy beacon]

[fallow cargo]

than i ll say whats the problem

[acoustic temple]

is this a hint really? or you just try to motivate him 😄

[wind ether]

I think the issue is that they assume that you guys are working together (which is prohibited), nothing with the solution itself

[fallow cargo]

well an accusation is more than an assumption

im doing this competition for fun

and this is not fun

[naive umbra]

🧂

[wind ether]

But are you guys working together? You mentioned “our solution” and seem to be familiar with the others

[fallow cargo]

everybody has a own solution

[craggy beacon]

btw my last flag is pickle, 22nd

[fallow cargo]

so i can say our solutions. I think it is correct in english

@wind ether

what im missing?

[wind ether]

Sorry, misunderstanding on my end. I was just trying to clarify the situation, not make any assumptions.

[fallow cargo]

Anyway i wrote privately to the organizer because for me it is bad and i think ill quit this competition

[gusty warren]

You said everybody has a own solution. But that's not even the key question. The key question is "Did you work together in terms of sharing information privately"

[brave briar]

The issue is that sharing methods, hints ... even if it is not complete solution is forbidden ! Everybody puts lot of effort to respect that on this discord. And in some way, if we all do that for fun, let's share all methods to all learn together.

[lost relic]

I have the feeling that hush was faster on previous days

[craggy beacon]

was very slow on weekends

[fallow cargo]

Well fine i selected my first submission... now im 4 and ill quit with this competition. So you are fine and happy...

See you everybody

[sturdy gorge]

🤨

[gusty warren]

Peolple keep saying don't overthink MNIST, but if I have no clue about the two numbers in input_data (well, tried a few obvious ideas that didn't work), am I overthinking or underthinking?

[nimble matrix]

I have stopped thinking about the MNIST and Pickle.

[gusty warren]

Pickle is fine, I have not solve it. But it pushed me to learn something new. MNIST is no fun at all.

[sturdy gorge]

Eager to know the solution to Pickle when the competition ends, seems fun, but out of reach currently

[indigo wedge]

Luigi here 🙋 I am sorry for your concern. It is true that we know each other, and we work for the same organization, but I don't think this was forbidden by the rules. We enthusiastically talked about the challenge because it is fun and... well, challenging. This is exactly how it is done here. We did not share more information than what has already been discussed on this channel. @olive ledge

[gusty warren]

Wow, I just realized what needs to be done for Passphrase during a shower and very confident about it! Next is just implementation. Encourage everybody to take showers when stuck...

[sturdy gorge]

aight, running to the shower

[olive ledge]

This is indeed not a teaming event as stated in the rules.

We (and Kaggle) understand this is a different type of competition for many of you, some confusion is to be expected. However, the integrity of competition is kind of everything, especially if we want to be invited back next year. All participants are responsible for reading and understanding the rules.

Please know that not only are there post-processing checks (the details of which will remain private), winners MUST also publish their solutions to be eligible for prizes.

That being said, we’ll bring this up with Kaggle and follow their guidance.

Please continue to CTF! ❤️

[indigo wedge]

Well, keep me posted, I'd be glad to stop wasting my life on passphrase if that's not necessary 🥲

[olive ledge]

No, please continue!

[violet trellis]

I suggest that all gold solutions should publish a write-up.

[waxen lynx]

I'm impressed by how trick is this competition, even a single word or a gesture exchanged in a circle of friends can be the key to solving a problem.

[devout jasper]

@violet trellis it doesn't solve the problem...
"I spent couple of days thinking about MNIST then I realized that blablanla" how can you spot a cheater?

[outer sundial]

Yeah in this competition it is really hard to do that as almost everybody have similar solution.

[devout jasper]

in this particular setup, the only thing you can do is to check the timestamps of submissions

[minor falcon]

Wait to see my writting with all i tried for inversion ahah

[violet trellis]

No solution for this of course. This is just better than doing it for the prizes only.

[outer sundial]

One guy actually deleted their account.

[olive ledge]

Continuing to talk about this is probably not productive. We will talk in the backend.

Also, there are still community guidelines to follow. Please ensure you are following those!

[past brook]

Maybe hush requires an italian accent

[hard perch]

Finally got MNIST. Now i wanna kick myself for not trying this first

'Don't overthink it' sounds so true now

[ornate marsh]

this gives me hope 😄

[queen garden]

Was stuck at 18 for 7 days. Got 5 in two days. I followed the best hint ever given : get some sleep.

[final path]

me: trying to sleep
my brain: lets try this idea for CIFAR

[exotic flame]

Please stop offending Italy and Italian, we are NOT in the same team, but against each other and having fun, we will share the codes, ideas and solutions without hide anything, and we are not in this competition to gain money, but to learn and having fun, like all the other kaggle's competitions. And btw, who can assure that N people are not collaborating together and creating a single fake account appearing as one ? If we were incorrect we would have done so...

Now hurry up! have fun and find the flags 🇮🇹 !

[past brook]

it was a joke

i wasnt accusing you lol

[amber totem]

Please stop guys, stay in the comp mind 🙂 It should be mostly fun for everyone

[craggy beacon]

yeah and please share what u discussed between each other

especially about inversion

[sturdy gorge]

getting some weird outputs that are neither the flag nor scores in semantle2 🤨

[craggy beacon]

ok for me

[ornate marsh]

[sturdy gorge]

I dont think they mean anything tho haha, just unexpected

[gusty warren]

running out of words to try, and the dictionary starting to come up with all sort of names.... lol

[runic trellis]

Man ofc we all belive you it is coincidance that 4 friends put solution (for probably same hard task) in 1 hour period and all get 23 points 🙂

[olive ledge]

Don't make me come in here....I'll make Granny 3 even harder.

[final path]

@olive ledge is the test_noise.wav somehow important for Hush, or it's just an example? (answer like "can tell" will be ok, but maybe that info won't be much of a hint)

[olive ledge]

It's an example.

[glass bay]

i feel the pain in that "mostly"

[glass bay]

sometimes Failed to process input pops up. Failed my search just now

[sturdy gorge]

ah, it was exactly that haha
with very different inputs, so got confused

[gusty warren]

Holy *, bathroom thoughts verified. Passphrase flag after 3 hours

[sturdy gorge]

another 24? 😮

[craggy beacon]

do u need to be a native english speaker for that?😅

[gaunt anchor]

Great ! Congrats ! I have also a plan for Passphrase once I am done with the current work on hush

[gusty warren]

I am no way english native.

[craggy beacon]

then it's cool because understanding the text of the task is a separate task indeed

[gusty warren]

embarassingly... I only have 18 flags so far...

[gusty warren]

I know it's cliche, but ...read the prompt

[craggy beacon]

u will catch up eventually

[final path]

Wow, getting Passphrase is impressive, congratz on this @gusty warren ! Think I gonna print the prompt and take shower with it 😄

[minor falcon]

i tried to register the prompt and fall alseep while listening it in loop, did not work.

[dense lodge]

Pretty much just look at what they did. First one decided to quit because he was 'wrongly' accused. Second one decided to delete his Kaggle account completely. FInally, this guy calls people out for attacking Italy LOL.

[severe pasture]

Probably best to just leave it to the organisers for now and stop speculating on it

[final path]

I don't think we need to discuss that as for now, because it's always a possibility of wrong accusations and without strong proofs it's not correct to write stuff like that, because it could be very harmful experience for other people.

[craggy beacon]

let's celebrate passphrase is being solved

[minor falcon]

has been known being solved* maybe other people already solved it without bragging :p

[dense lodge]

sure and let other people with high scores know that they can inflate the leaderboard with alt accounts and friends' accounts

[final path]

yeah, disclosure of hard tasks being solved can be bad for you leaderboard place but surely gives hope and motivation to others 🙂

[gusty warren]

True. I probably woldn't talk about it if I were on top of the LB. Getting the passphrase won't get me gold since I started late, but may stir up the LB a bit by letting people know passphrase is sovable by a noob like me.

[minor falcon]

oh yeah, i'll be the first one to brag when i crack grany 3 ahaha

[hard perch]

For some LLM problems(Witf), I got a flag with some prompt, but then when I re-run with the same prompt, it gives different output(not the flag). Will this be an issue later while submitting the NBs?

@olive ledge

[limber flower]

As long as you achieved the flag once, there shouldn't be any issues. The LLM challenges are non-deterministic to some degree and we'll respect that.

[gaunt anchor]

Once you see it .... you see it ... its not the coding that is hard ... its seeing the solution 🙂

[gusty warren]

Is there a CLI command to submit for this competition? I accidentally submitted a file with empty(literally empty) flag, the submission gave an error, and the submit button on website is broken ever since. Cleared cookies, logged out logged in, changed browswer, none worked

[craggy beacon]

create new submission notebook?

[gusty warren]

makes sense, let me try

[random minnow]

"True. I probably woldn't talk about it if I were on top of the LB. "
