Hey guys, has anyone completed the 'Attacking Kerberos' room? I'm stuck on task 7 but I'm not sure what I'm doing wrong.

Hi there looking for a hint with the room GraphQL, question 1 task3 (pretty sure my query is good but can't find out after hoooooouuuurs). Thanks

fallen sorrel
#

Ignore my question - I figured it out.

shell dawn
#

Anyone done graphql room?

stuck fractal
#

It's always best to just directly ask your question.
If someone can help, then they will.

shell dawn
#

Can't find the flag

#

In graphql for user Para

#

If there is one

#

Lmao, nvm. Sorry. I was looking for a flag. Got the hash.

#room-hints is here for people who want a "pointer" towards the room they are completing, and not necessarily a spoiler. As such, when asking a question, be sure to include:

  • What room you are on
  • At what stage are you stuck exactly? Enumerating? Exploiting? Priv esc?
  • What techniques / tools have you tried so far? Just so that we know how to hint you in the right direction without repeating what you've already done.

I am stuck at Enumeration part , I found some encoded strings , unable to decode one of them

Hello! I'm currently doing the Bolt room and I think something's wrong with my metasploit.

#

[*] Started reverse TCP handler on 10.9.190.109:4444 
[*] Executing automatic check (disable AutoCheck to override)
[+] The target is vulnerable. Successfully changed the /bolt/profile username to PHP $_GET variable "hutayc".
[*] Found 3 potential token(s) for creating .php files.
[+] Deleted file mvfpeduf.php.

^C
Abort session 1? [y/N]  n
[*] Aborting foreground process in the shell session







So I'm still waiting for it to connect

stuck fractal
#

You might not have a prompt

#

Try backgrounding and foregrounding it

distant violet
#

Can you explain foregrounding? What is that? hahh

stuck fractal
#

Control Z to background the session

distant violet
#

I did that.

stuck fractal
#

Then sessions -i putTheSessionNumberHere

#

Should I reboot the box or connect to it using SSH?

stuck fractal
#

Surely you can't use SSH?

distant violet
#

I didn't try

stuck fractal
#

You don't have any creds that work for SSH

distant violet
#

Don't I have the username and the password?

stuck fractal
#

You probably don't have a prompt but do have a shell

distant violet
#

Or those are just for the CMS

stuck fractal
#

Don't I have the username and the password?
@distant violet For bolt yes, they shouldn't be the same

#

It's a different service

distant violet
#

Oh, alright

#

The task requires me to "Look for flag.txt inside the machine."

stuck fractal
#

Yeah

#

So you need to use the shell that you got from exploiting the service

distant violet
#

But I cannot get to connect, so should I terminate, and deploy again?

stuck fractal
#

You probably don't have a prompt but do have a shell
@stuck fractal

distant violet
#

Oh

stuck fractal
#

it did connect

distant violet
#

So what do I do now?

stuck fractal
#

Try running a command like id in that session

#

See if it works

distant violet
#

/bin/sh: 2: id: not found

stuck fractal
#

You have a shell

#

whoami

distant violet
#

in fact yes, help does work

stuck fractal
#

So you can use that shell to get a more stable shell

distant violet
#

whoami root

stuck fractal
#

Is SSH open?

distant violet
#

Yes

stuck fractal
#

My recommendation would be to add an authorised key to root and then try to SSH in from another terminal tab/window

distant violet
#

That's hard, I think

stuck fractal
#

That gets you a MUCH more stable shell, with the caveat that it only works for users with SSH enabled

#

It's not very hard

distant violet
#

Shouldn't I just try to get the flag through the msf?

stuck fractal
#

Copy your public key into /root/.ssh/authorized_keys

#

You can

#

But that shell is a pain and doesn't give you tab completion ETC

#

A full ssh session is more stable and more interactive

distant violet
#

I am able to ls and everything, but I cannot seem to find the flag.txt

#

Nevermind, I did cd .., a few times and I found it 2708_happydance

stuck fractal
#

I fully recommend learning how to use the find command

#

It's super useful

distant violet
#

I tried to use it and I just did "find flag.txt"

#

I wondered why it didn't do anything hahh

#

Well, thanks for the help. Deja_Black_Hearts

stuck fractal
#

locate follows that kind of syntax but works slightly differently

distant violet
#

I kinda need help installing john. Could you help me or isn't this the specific channel for this?

@distant violet there's some great articles for it.

@distant violet there's some great articles for it.
@stuck fractal I don't really know how could I google this

lxd privesc

distant violet
#
Package lxd is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'lxd' has no installation candidate
stuck fractal
#

You need to very carefully consider where each command is being ran

distant violet
#

What do you mean?

stuck fractal
#

You gave no context with the error message

distant violet
#
root@andrew:~# sudo apt-get -y install lxd
Reading package lists... Done

Does this help?

stuck fractal
#

You don't need to install anything on your machine afaik

distant violet
#

You don't need to install anything on your machine afaik
@stuck fractal Then how could I run lxd?

stuck fractal
#

Where are you trying to escalate your privs?

distant violet
#

On the room Gaming Server, I'm trying to use lxd to escalate privileges so I can get to root.txt

stuck fractal
#

Exactly

#

So why are you running stuff on your own machine?

distant violet
#

Well, how could I sudo on the server

stuck fractal
#

You don't need sudo

#

That's the point

distant violet
#

I mean I have to build alpine, right?

stuck fractal
#

Yeah, use the script

distant violet
#

And it says "must run as root"

#

Let me try again

stuck fractal
#

The article explains this

distant violet
#
Cloning into 'lxd-alpine-builder'...

I think it hanged

stuck fractal
#

It's working

#

Give it time.

distant violet
#

Alright, as you say.

#
Cloning into 'lxd-alpine-builder'...
#

Still waiting

white salmon
#

Read the exploit and make sure to be on the right machine for each step

distant violet
#

Wait, so I should download alpine-builder on the attacker machine or the remote machine?

stuck fractal
#

Your machine

distant violet
#

I did this.

stuck fractal
#

The target machines do not have internet

distant violet
#

I have alpine downloaded, and have builded it

#

But LXD isn't working on my machine

stuck fractal
#

You should be able to follow the instructions in the article

white salmon
#

If we are talking about the same exploit then you can see:


# Step 1: Download build-alpine => wget https://raw.githubusercontent.com/saghul/lxd-alpine-builder/master/build-alpine [Attacker Machine]
# Step 2: Build alpine => bash build-alpine (as root user) [Attacker Machine]
# Step 3: Run this script and you will get root [Victim Machine]
# Step 4: Once inside the container, navigate to /mnt/root to see all resources from the host machine
distant violet
#

Indeed, we are talking about the same exploit. So how can I transfer the script to the victim?

stuck fractal
#

You don't

distant violet
#

So, I run it on my own machine?

stuck fractal
#

Yes

#

Install LXD

distant violet
#

On my machine?

#

If that's the case, I cannot.

stuck fractal
#

apt update and try again

distant violet
#

Same error.

#

Nmap room

What switch should I include if I don't want to ping the host?

Can I get a hint

stuck fractal
#

Have you checked the nmap manual?

ornate iron
#

yes

#

Can you specify which category pls

stuck fractal
#

Control F ping?

ornate iron
#

what's that?

#

I probably meant which section does the answer fall into

stuck fractal
#

Search for ping

ornate iron
#

oh ok

Hey there, i'm experincing an unusual problem.. room "Web Scanning", task 3, question #8
is it normal that i can't find the right answer in the alert tab?

woven mirage
#

which room? i couldn't understand your question, elaborate it more

maiden kite
#

sorry, i hit enter b4 my question was finished ๐Ÿ˜…

woven mirage
#

the answer should be in the alert tab...

#

hmmm...

#

try to scan again?

maiden kite
#

scanned like 10 times already

stuck fractal
#

The alert is deprecated

#

It will no longer show up

maiden kite
#

ok... so how can we possibly know the answer just by doing the room?

stuck fractal
#

The room needs updating.

#

It's a known issue

#

It's on the list.

ow, ok thanks! i can't see that issue on the room. that's why i asked ๐Ÿ˜‰

I still need some hint on YOTD

wicked rain
#

@indigo ridge pay attention to the errors. some attack is mentioned. combine it with above hint and do some research.

young tide
#

@cedar axle it is and I already know how JWT tokens work I just have no idea how to decode the signaturesecret

indigo ridge
#

@young tide there is a npm package for that.. use google

@young tide damn, that's a premium room, cant help, I'm a poor student. i live on packet noodles

young tide
#

@cedar axle aye one of this days you'll get that premium room I just grabbed it to test the skills that I've learned from a certification body and so far so good the only thing left for me is the one that I asked about and the juiceshop

#

it's the 3rd part of JWT that I need to decode @cedar axle it dosn't appear on jwt.io

woven mirage
#

I don't have access to the room, but if the algorithm is none, jwt just uses plain base64

cedar axle
#

yeah, it could be a weak secret or you just alter the alg to none

#

not sure exactly as i cant run the lab

young tide
#

there's nothing in the lab

#

I just need to get the 3rd part of the JWT token

cedar axle
#

the room i mean

#

right i thought you had to login to the page

young tide
#

1st is the header which has the typ: none
2nd is the payload
3rd is the secret I need to get the secret

#

it was just right in front of me and I just read about it before the challenge

#

@young tide jwt-cracker worked for me

young tide
#

Thanks @cedar axle yes that was the one that was needed

#

took me like 7 hours for that question and a hint

#

OMG

cedar axle
#

sometimes it's the trivial sh#t that trip's you over

Hey guys,
WackoPico Web App Room, does usernames extraction require using burp intruder ?

What's the room code?

limber iron

#

title ?

#

woven mirage
#

What task?

young tide
#

If you meant username enumeration the answer is it's not required although doing it manually might take you hours or days

limber iron
#

What task?
@woven mirage Task 4) Question #4

#

If you meant username enumeration the answer is it's not required although doing it manually might take you hours or days
@young tide haha yes thats the problem

woven mirage
#

I just looked up the writeup

#

Well, you can use burp intruder if you want to brute force

#

But you can find users without brutefoercing at all

#

Try to create a user and check how can you exploit an url param in one of the pages to view info about other users

limber iron
#

ahhhhhh i see noww

thanks buddy

Rule 13: When asking for help/tech support please perform research to your fullest ability. Mods and Community Mentors have the right to refuse helping those who have not done troubleshooting/research on their own first. Clearly phrase your questions as we (fortunately for all parties involved) cannot read your mind. Please include the room, task, and question number in your question if possible.

Although we are a learning platform, we politely ask that you respect the competitive nature of newly released challenges. As such, no hints for new challenge boxes should be given immediately after a release (72 hours, by default), unless instructed otherwise by the content creator.

hello, i'm working on the burp suite room...i'm on task 11 and i'm lost on stop 1..."Let's first take a look at decoder by revisiting an old friend. Previously we discovered the scoreboard within the site JavaScript. Return to our target tab and find the API endpoint highlighted in the following request:"..... i am confused about this scoreboard reference, I went back through the entire room and can't find any information on it and its not showing up in my site map...

median compass
stark parrot
#

ok...how would i have known that?

#

when did we previously discover the scoreboard?

#

my burp crashed on one of my previous steps... i had to restart it

median compass
#

honestly I don't remember, I've used juiceshop a lot in the past though and i know it from there

stark parrot
#

its possible i lost some information when that happened

#

i just want to understand what i missed

#

really frustrating, as i've gone back through the birp suite room multiple times now and see no reference to this scoreboard they speak of

median compass
#

finding it is actually a task on the juice shop scoreboard

stark parrot
#

cool, the room references a task not otherwise discussed in the room. makes sense

#

thank you for the help

#

so i don't understand the preferred course of learning then. why isn't this covered ahead of time? i'm following the course under dashboard, completed welcome and metasploit, moved to vulnersity and was sent over to birp suite room as a prereq

#

this is all very confusing for someone who just wants a progressive path

#

they speak on the scoreboard as if we covered it in the room but we didn't.... lol

#

am i starting at the wrong spot?

median compass
#

what I will say is that the very first lesson this site tries to teach you is to research

#

a quick google for "owasp juice shop scoreboard" will answer your original question for example

#

no, just be patient and keep at it, and always be prepared to fill in the gaps with a little googling outside of the provided content and hints

#

some discord problems there, seems like half my messages got lsot

stark parrot
#

i think. i definitely appreciate you helping me through this

median compass
#

you can use #room-bugs to leave some feedback on the room if you want

#

a community user's tutorial?

keep at it and you'll get there, patience, time and persistence pay off with this stuff

Hello guys! I hope you are doing alright!
Yesterday I tried "Jack" (https://tryhackme.com/room/jack).

I checked the writeup to see how to escalate privileges in WP and all of them are exploting a plugin.
But neither with wpscan nor after being logged I am able to find the plugin.

#

I finished the room but still fail to see how people found that plugin

true prairie
#

I know what you mean. Did you check the possible commands and options you can use with wpscan?

bold star
#

first time using wpscan

#

I check the help command and found:
-e p and ap

I tried popular plugins first -> no results
I tried all plugins -> no results

red minnow
#

@bold star the plugin is called User Role Editor

true prairie
#

As far as I know wpscan emunerates the plugins with passive detection. There is an option to change that. Try this with the most popular plugins :)

bold star
#

I know the plugin by checking the writeups and the rest went smoothly.
Thank you @true prairie! I will check the options again โค๏ธ

You are the best! It was at the end of the help screen

Hey guys! Hope everyone is good! Iโ€™m in the middle of room Brute IT and stuck in task 3 question 1 whatโ€™s user:password of admin panel, tried to brute force it with hydra but getting false positive results can anyone give hint?
@wicked plaza That's still a new room, please wait 72 hours from room release before asking for help or hints

key for first cipher was like twelve characters

#

even if it was bruteforcable i really would prefer to do it legit

#

a nudge from someone who has actually done the room?

true prairie
#

Without brute force you should read through the email again. It isn't really a key but a word that really gets mentioned noticeably

rose cape
#

ok thanks

#

got it feeling stupid gracias @true prairie

true prairie

Not a problem. Felt stupid as well. Seems so obvious looking back at it

  • What techniques / tools have you tried so far? Just so that we know how to hint you in the right direction without repeating what you've already done

Hey I am running into an issue with brute it room I run hydra and get 16 useable passwords but nun of them work

You are using the wrong command and it's giving you false positives most probably

Can't actively help with the room as it's not 72 hours old yet

Hello! How everyone is doing? I just learned Privesc on Linux in the Complete Beginner path and I wanted to practice it on a room. So some advised me Wonderland but I'm stuck right now ๐Ÿ˜…
I successfully logged in alice account and performed a LinEnum scan. I tried some suid files, checked cron, checked /etc/passwd but no luck.
I think I need to horizontaly escalate to find user.txt as I think it is in rabbit directory but I'm running out of idea.

stuck fractal
#

It's something you'll find very quickly with enumeration, but you might not know how to exploit it

dusky remnant
#

Do I need to put this aside and come back later when I learn more about linux and/or privesc?

stuck fractal
#

Nope. You can probably find a method with a couple google searches about what you're seeing

#

Something relatively obvious now that you're logged in as Alice. Something you should always check for privesc.

dusky remnant
#

I'll put next sentences as spoiler if it's okay. I'm not sure about what you're talking about

stuck fractal
#

sudo -l is awesome

#

Something you should always try

#

Then it's a matter of researching what you're seeing

dusky remnant
#

|| Do you mean sudo -l? I saw something like (rabbit) python3.6 but I don't know what does that mean and how to use it indeed ||

#

Alright

#

I was right then. I need to check it you're right

hello everyone. in the linux challenge room task 2 #4. im getting an error trying to open up a specific file saying i dont have permissions. i went into a specific folder where the cronjobs are created and i see the file or folder or whatever it is and i cant access it

#

please gimme a hint

#

i already went back to bob to see if he had privileges but he doesnt

stuck fractal
#

It's a different place

#

It's a file you definitely have permissions for

#

Keep looking

wind peak
#

james i dont want to give away anything can i message you privately

stuck fractal
#

No

wind peak
#

okay ill go look elsewhere

stuck fractal

I put 99% odds on you currently looking in like, var/spool/cron or something

wind peak

thats where i am

lol

Which is where the cron processes start or something

But not where they are created

That file is not the right thing. So no

Do you understand what a rabbit hole is in CTF?

wind peak
#

im trying to grep for the characters c9. so i used this command find / c9 | grep c9

#

but its coming up with alot of unnecessary stuff

oblique cliff
#

That would be finding files that contain c9

#

Iโ€™m assuming youโ€™re doing the one that wants what is in the file to be c9

wind peak
#

yup

oblique cliff
#

So Iโ€™d suggest looking a bit deeper into how to use the find command

#

Cuz thatโ€™s not doing what you think it is

wind peak
#

okay thanks

Files that contain "c9" in the file name, more accurately

guys, I'm trying to solve the room advent of cyber. Right now in day 1. When I try and decode the value of the cookie for the 2nd question. It says incorrect even though I've verified through hash identifier and it turns it to be base 64. am I going into a rabbit hole?

stuck fractal

It is asking for the static part, right?

There's one part that changes, and one part that stays the same.

Honestly, I have no clue. I'll just show you the cookie

Show me the question instead

That'd be more useful to me

Yeah

So there's part that varies by user.

does the linux final challenge has something to do with "man page of sudo is very nice "

not sure if that's a question...

you mean the "Learn Linux" room?

do you have the user ||nootnoot|| ?

im trying every user name and password i see

in there

let's see if one matches

and trying to get into hidden areas

using find

ok, one good strategy in general is to look for every user that you do have for files that they own ||find / <-user/-group>||

please don't tell how to get

everyone im not opening spoilers

anymore

don't look at the spoilers if you don't want them, that's why they're hidden

ok

median compass

one of your existing users has a file in an odd location, happy hunting

small oracle
#

hmm ๐Ÿค”

median compass
#

and eventually yes, sudo is part of it, to answer your original question

small oracle
#

@median compass existing means shiva1-4 ?

median compass
#

shiba1-4 yes

small oracle
#

hmm ๐Ÿค”

#

is ll file a part of it ?

#

it prints 1-1000 on

#

cat

median compass
#

what file?

small oracle
#

ll file in noot i guess

#

the name of the file is ll

#

double ll

median compass
#

not sure what that is - you've already used find in Task 31, question 3, just use that with your shiba users, one file should pop out for you

hidden fractal
#

is it normal that nmapping takes so much time?

median compass
#

it can do @hidden fractal, depends on how the box you're scanning is configured

final mortar
#

Also depends on "what" and how you are scanning

#

What options are you using

hidden fractal
#

is it not about wifi or anything?

final mortar
#

No, it's usually not

hidden fractal
#

What options are you using
@final mortar -A

final mortar
#

-A takes time, cause it' discovering a lot of stuff

#

Just like a full port scan -p- takes time

#

You can use -vv so check how much your scan is done, what ETA and stuff like that

#

You can also speed your your scans with -T4

median compass
#

you can try rustscan too @hidden fractal, sometimes having different tools for different situations is a good thing

cedar axle
#

if you just want to list open ports masscan is good

#

what is the meaning of rabbit hole in case of ctf can someone explain ?

median compass
#

a rabbit hole is something that looks like a useful direction to find an exploit but actually goes nowhere

oh

#

they teach you to not stop looking for ALL interesting things just because you find one

cedar axle
#

rabbit hole = red herring

@median compass i looked for every user using command i used every user except shiba4 is same

but shiba4 is already used

hello, i'm still struggling with this SteelMountain room, specifically access and escalation without metasploit. so I did some googling and everything is telling me to start SimpleHTTPServer on port 80. Can't get that module to load in python3, so run python3 -m http.server which works but won't start on port 80 cause something is already listening on 80. Box shows 2 processes listening on port 80, when I kill them both, my attackbox becomes immediately inaccessible... what am I missing

median compass
#

i think you want to be running the web server on your attack box @stark parrot, the purpose of the server is to allow the exploit to pull across nc.exe

stark parrot
#

understood, thats where i am trying to set it up

#

but there are 2 process already using port 80

#

and everytime i kill the process, my attackbox is un-usable, i have to reboot it

median compass
#

your attack box is running a webpage?

#

can you show me?

stuck fractal
#

If you full screen the attackbox

#

It uses a service on port 80

stark parrot
#

oooooooo interesting

median compass
#

ahhhh you're not on a VM, gotcha

stuck fractal
#

If you use it in the small window it seems fine. Might also be able to SSH in?

stark parrot

let me test

very interesting lol

#

when i kill process 2349, immediately lose my attack box

#

so i can't bind anything to port 80

#

i guess maybe i should look at using my own vm

#

same problem if i use split screen view on the VM

stuck fractal
#

Yeah I'm talking about the small window on the my-machine page

#

Or ssh in

median compass
#

if you ssh in you'll lose the GUI when you kill that process but you'll still have a command line and be able to continue

stark parrot
#

ok, sweet

#

i can ssh directly to the attackbox on the public ip?

#

thats too easy

stuck fractal
#

if you ssh in you'll lose the GUI when you kill that process but you'll still have a command line and be able to continue
@median compass You'll lose access to the gui from the fullscreen/splitscreen

#

It still exists etc

stark parrot
#

yeah this should work, i just ssh'd to it

lets see what i can do

sure, they'll have lost it though, I was simply making it easy

So, flag13 is somewhere in the 2 scripts of the Titanic movie. I tried to do an egrep to find flag, and it only found the flagpole to which they clung.

@rose cape, anything mountable can be found in ||/dev|| have a look there to see if anything jumps out

Didn't realize we had a diff command. Popped right up. Ty

I found the kernel version! Woohoo!!

I'm really not sure what I'm supposed to do with that. I'm trying to see if there are other ways of finding that info with the hope that there will be something nearby to show me the way.

stuck fractal
#

That's for a specific question in Linux Challenges right?

stone oyster
#

Yessir

stuck fractal
#

There's multiple ways to find the kernel version

And there's a flag that you'll get with one of them

stone oyster

Yeah. I have the kernel

stuck fractal

Yeah

#

But not the flag

stone oyster
#

Yeah. I was hoping it would be like that.

stuck fractal

So keep going

#

The hint is /etc/*release right?

#

There's a hint there

stone oyster
#

hint???

#

second window was covering that.

#

just *release

stuck fractal
#

That's a bash/shell glob

stone oyster
#

yeah. got it.

Look into that and you'll get the flag

stone oyster
#

ty

stuck fractal
#

Cool, good luck for the rest!

stone oyster
#

I saw mention of the first part of that file and knew what I needed.

#

I'm doing a whole lot better with this than i was. I'm loving it all the more.

#

Something that I've noticed is that most flags, when you go to enter the info, require one hand on alpha and one hand on numeric. Was there a reason for that?

stuck fractal
#

They're md5 hashes usually?

#

Usually you copy/paste them

#

SSH in and you can actually copy/paste easily

thx

#

how do i search a process thats using a port. i tried ps but couldn't find it. some reason my meterpreter decided to make 5 sessions on multiple ports

stuck fractal
#

Huh?

#

What are you trying to accomplish here?

white salmon
#

tried port 4455 also in use

stuck fractal
#

Ok, but what are you actually trying to accomplish here?

#

LPORT shouldn't be 445

white salmon
#

i have a meterpreter on blue on 445 right

stuck fractal
#

That's the RPORT

white salmon
#

and now im trying to use shell_to_meterpreter

stuck fractal
#

You don't need shell_to_meterpreter

#

Do you know what shell_to_meterpreter does?

white salmon
#

im following the ctf

#

yes

#

i no i can do sessions -u id

it converts a plain shell to a meterpreter

or type shell

You don't have a plain shell, and you already have a meterpreter

white salmon
#

why is the ctf telling me to do that?

stuck fractal
#

because metasploit changed the way default payloads work

#

Side note: It's a room, please call it a room

#

Not all rooms are CTFs

white salmon
#

right

#

but when i type getsystem no privs

stuck fractal
#

You're already nt authority.

white salmon
#

wait now im able to getsystem before i wasn't#

#

how do i know which hash it is btw? i tried hashid

halcyon bay
#

how do i know which hash it is btw? i tried hashid
@white salmon may be dumb but have u tried hash identifier ?

white salmon
#

that's what hashid is right?

#

nm i figured it out lol

stuck fractal
#

how do i know which hash it is btw? i tried hashid
@white salmon Context is the best way

#

You dumped it from a windows system's SAM file, it's going to be NTLM or LM

white salmon
#

i mean i should have noticed the machine lol i was being dumb

#

how do i word the hash into a textfile though i have never cracked a nt hash before

stuck fractal
#

You place the string

white salmon
#

do you include the entire string

stuck fractal
#

This sounds like a great thing to google

#

"How to crack ntlm hash"

white salmon
#

i tried too but its just on cracking not placement of the hash

stuck fractal
#

Find a better guide then

#

You need to identify what part the hash is

#

then put it in a text file (or find a different way)

white salmon
#

true i'll look

solemn smelt
#

you can just yeet the entire thing into a file

#

or you can use the hashcat example hashes

#

that will help you understand the parts of hashes and what each one looks like

stuck fractal
#

or crackstation because ntlm is rainbow-table able

white salmon
#

yeeting the entire thing into a file worked lol

Can someone give me a hint what a "flag" is? What am I looking for?

Asking for Task 5 Find Flags room/blue

median compass
#

flags are little pieces of text hidden in the rooms at certain points, when you've gotten past a certain stage the flag is your reward and proof that you got there

#

sometimes they're in a file (often flag.txt, or user/root.txt)

#

or they can be hidden in another file

#

usually they have a recognisable format, like THM{ text }

white salmon
#

where do i find the bin/recycle directory on windows machine

#

better yet how do you use a command like find on windows?

stuck fractal
#

Have you googled that?

white salmon
#

i haven't lol

stuck fractal
#

One of the most important skills in infosec is research

#

You are expected to do your research before asking here too

white salmon
#

i do but sometimes i get the wrong answers on google

solemn smelt
#

get better at googling is honestly the only answer to that

#

google doesnโ€™t mess up your query does

white salmon
#

im trying to complete them without watching the videos

naive vortex
#

thx @median compass โค๏ธ

white salmon
#

could i get a hint on the 2nd flag T5 i checked bin

stuck fractal
#

I wish I wrote down where I kept my password. Luckily it's still stored here on Windows.

#

Where are password (hashes) stored in windows? Have a look there

white salmon
#

thanks

finally completed lol thanks @stuck fractal

Hello- In room 283 (Network Services) Task 4. when using smbclient I am trying to get the information and put it on my attack machine. the command i use while in smb is "get "Working From home Information.txt" interesting1.txt. The response I got was NT_STATUS_DISK_FULL. When I look on my attackbox it shows that the file was transferred into interesting1.txt but there is nothing in the file. can provide screenshot if necessary. Is this a memory issue for my VM?

stuck fractal
#

Storage issue with your VM most likely

#

Also, the rooms aren't numbered?

#

IDK where you're getting the numbers from

astral smelt
#

It seems like they're getting the numbers from the upvotes of the room

queen hull
#

ah thats what i thought the number was

stuck fractal
#

Rooms are identified by their titles, and uniquely identified by their room code (the portion of the URL after /room/)

queen hull
#

Well I changed the storage in my vmware settings and it now has me using rolling kali tty1. troubleshooting how the heck that happened

lyric crystal
#

Hello guys, just a question, in many paths they refer pass.txt

#

After tons of wordlists i couldnt crack the hashes

#

Any idea of specific wordlist or where pass.txt is located?

median compass
#

i think that might just be a placeholder @lyric crystal

#

are you using kali?

lyric crystal
#

My own attack box (ubuntu)

median compass
#

ok, in most of the THM rooms passwords are used from the rockyou.txt password list

lyric crystal
#

Tried that!

median compass
#

well, in some rooms the hashes aren't crackable

#

in that case there's always another way to get where you need to be

lyric crystal
#

Its the off sec path, so has to be crackable

median compass
#

like, if i just take 16 completely random characters from /dev/random you'll never crack it (edit: not with a wordlist at least)

#

what room is it?

lyric crystal
#

Under the path off sec

#

The active directory/ kerberos

#

But i ve seen it in other rooms as well

stone oyster
#

Working on LInux Challenges. I'm up to flag21.php. Trying to figure out how to display it. I used cat and it got the message, but, I guess I'm at a loss as to what I need to do. Got a nudge for me?

median compass
#

well, you can try seclists too

stuck fractal
#

Use rockyou unless you're told otherwise @lyric crystal

median compass
#

they have good lists, but yeah, it's usually rockyou if it will crack at all

lyric crystal
#

I ll try it again guys, thanks, already used most of the seclists

median compass
#

then you also have to be sure you're cracking against the right service, like hydra may get nothing against SSH but succeed against SMB

stone oyster
#

I started to pull up VisualCodeStudio. Then realized I couldn't move the file. I've tried opening it in web browsers.

lyric crystal
#

Already collected the hashes and recognized successfully by hashcat

#

Im not that stupid lol

stone oyster
#

We are all that stupid. We start somewhere

median compass
#

that wasn't my implication, it's not easy to cover every possible scenario on the information given

lyric crystal
#

Anyways..thanks again!

median compass
#

@stone oyster try looking at the raw file, you want to see everything in it, not a rendered version

stone oyster
#

I see the message MoreToThisFile

#

do I need to hash that?

median compass
#

you could try what I hinted first ๐Ÿ™‚

stone oyster
#

raw file?

#

will look into that.

#

I assumed cat was the raw

median compass
#

imagine you wanted to look at the contents of a binary file

#

how would you do that

stone oyster
#

I hate to say it, but I don't know. But I will research and see if I can find an answer.

#

Ty

median compass
#

if you try googling "look at the contents of a binary file" you'll find it pretty quick I'm sure

stone oyster
#

thank you.

#

I didn't get that explicit with my search.

median compass
#

if this all seems very cryptic that's because this is #room-hints, we try not to give the answers but nudge so you can find them yourself

stone oyster
#

I know. I get that.

#

I don't like having the answers given to me.

#

Most of the time a nudge is all I need.

#

lol

#

Most of the time.

#

Oy....so take the code and decipher it?

median compass
#

nope

#

the very first link in google for me has the answer

stone oyster
#

I have a stackexchange link

median compass
#

me too

stone oyster
#

k

#

I did the xxd and was given a 5 line code

#

Do I need to go further?

median compass
#

did you read what you got?

#

i'd recommend man xxd too and learn a little about a very useful command

stone oyster
#

On the right it's the same text as if I cat. I ran it thru a hex decoder and it showed the same message.

#

The answer isn't the typical flag of long code.

#

it's 6 characters

median compass
#

ok, can you copy the output here in spoiler tags? (surround it with ||)

#

cause it shouldn't show you the same message

stone oyster
#

lol

#

I tell ya' what. I gotta' get for now. I will look into man xxd later and see if there's something that I missed.

#

Thanks for the nudge.

median compass
#

k

stone oyster
#

Is it ok to send you screenshot?

median compass
#

sure

stark parrot
#

man this last steel mountain task is really kicking my erse lol.... i've actually gotten to the point where i've replaced the ASCService.exe with my file and i'm able and start the service. netcat responds and says the connection is received, but i never get shell access

stuck fractal
#

Use a multi handler.

#

Set the payload correctly

#

If you're using a staged payload then you 100% need multi handler ss your listener

stark parrot
#

got it, worked like a charm, thanks

white salmon
#

On basic pentest what is the correct way to display the smb information of users?

#

The attackbox doesn't have enum4linux and i cant install via apt?

stuck fractal
#

It's got it as a script on the system

white salmon
#

where?

stuck fractal
#

Cmn said recently

white salmon
#

cmn?

stuck fractal
white salmon
#

ahh thanks

#

still managed to get one user without it lol not sure that was intended

#

okay im extremely stuck on the priv esc there is no linenum

#

ahh okay it's in the additional tools

#

how do i run the linenum on the ssh server?

solemn smelt
#

you transfer it and run it

white salmon
#

how to transfer i tried google and scp but the file wasn't there?

solemn smelt
#

scp, wget and http.server, you can just get it straight from the linenum github

#

lots of ways

white salmon
#

didnt think of that thanks

#

okay so wget doesn't work and http server no module?

#

tried nano aswell?

woven mirage
#

Well you can't wget like that because the machine doesn't have internet connection

#

And in the scp command just remove the last / in the directory, try /home/jan instead of /home/jan/, not sure if that's the problem though

white salmon
#

Didnt work it just has no output and when i check the files not there

hollow maple
#

Try copy to /tmp

white salmon
#

I tried that too the files just arent copying over i cant nano the file because of root privs ill just come back to it. Only need the last password.

hollow maple
white salmon
#

Python has no module named http.server i could script it but meh. The wget just sits and hangs on connecting i think its the attack box ill try it on a vm instead

hollow maple
#

Wait, only python?
Try: python -m SimpleHTTPServer

white salmon
#

I tried that same error message lol

hollow maple
white salmon
#

Lmao ๐Ÿ˜ฉ

woven mirage
#

just try pip3 install httpserver

hollow maple
#

But he need internet, right? AttackBox has internet?

white salmon
#

Its just hanging again? Did i go over minutes or something

woven mirage
#

attack box has internet

#

machines in rooms don't

white salmon
#

I had to watch the video included. I followed what he did with scp to a t. And still nothing

woven mirage
#

scp command should work

#

send screenshot of your scp command

white salmon
#

It doesnt transfer

#

And /tmp

stone oyster
#

I just want to make sure I know what I'm seeing and thinking. For the Linux Challenges room, flag23, the directions say to find it, then reverse it. They want me to report the flag backwards?

white salmon
#

If its a file it means reverse engineer usually.

stone oyster
#

and yet, I tried typing it in backwards and it went.

#

That was just kind of unsettling in my head.

#

Maybe I'm tired.

hollow maple
#

@white salmon I started an AttackBox, logged as jan, used wget, linpeas.sh was copied and running ok, that's crazy..

white salmon
#

What directory did you use

hollow maple
#

/tmp

white salmon
#

What the hell

hollow maple
#

Basic Pentesting, right?

#

SCP tested, and it's ok.

stone oyster
#

Flag24, the C compiled flag. I tried the gcc and no matter what I do I keep getting a list of what looks like errors.

hollow maple
#

Linux Challenges?

stone oyster
#

yeah buddy

hollow maple
#

Sorry, I can't help, don't have access to this room.

stone oyster
#

It's not paid

#

If it is, then I shouldn't be able to get in.

stuck fractal
#

It is a subscriber room

hollow maple
#

You're subscriber, so you can access..

stone oyster
#

oh.....interesting.

#

lol

#

Maybe the last payment I made hasn't run out yet.

#

So...I did ./flag and get the message.

#

Checked the hint and it asks who can access. I know who can access.

stuck fractal
#

So I need to do the absolute most basic reverse engineering

#

It's suggesting a program that finds strings in files

stone oyster
#

oh.

clear saddle
#

Anybody open for a ?

stuck fractal
#

@clear saddle It's always better to just directly ask your question. If someone can help then they will.

#

We don't know if we can help unless we know the question, after all

clear saddle
#

I know how to shh but the password for the linux course must have been changed.

#

it says use shiba 1 but this does not get me in

stuck fractal
#

You don't share virtual machines

#

The password hasn't been changed

#

Make sure you're deploying the Learn Linux VM not the attack box

#

They're totally separate.

stone oyster
#

If you wanna' ask about programming, one of these folks can help. If you wanna' ask about comfort food, then ask me.

stuck fractal
#

Don't use that word here, it's a slur

clear saddle
#

My apologies

#

I do not see the Learn Linux link

stuck fractal
#

In task one

#

There's a deploy button

#

VMs are attached to tasks rather than rooms. A room is made up of several tasks. A task can have: a download, a VM, or neither attached.

clear saddle
#

I got now. thanks so much

#

I appreciate the help @stuck fractal

stone oyster
#

Is the message in the flag24 file supposed to suggest a command/program to find a string with?

#

or just suggesting that i do that?

stuck fractal
#

The question itself suggests that you do that

stone oyster
#

ok. thank you.

stuck fractal
#

Analyse the flag 24 compiled C program. Find a command that might reveal human readable strings when looking in the source code.

stone oyster
#

Is there a particular way or command or program to use?

stuck fractal
#

Yep. A specific command makes it easy

stone oyster
#

ty

stuck fractal
#

@inland onyx also, it shouldn't say source code here. linuxctf task 4

#

You're not looking in the source code, considering you're looking in a compiled binary

stone oyster

I'm going to bed, but I found what I need to do the work tomorrow.

#

night ya'll.

thanks for your help.

Guys, for y'all that completed the zthlinux room (the one that teaches some commands, ssh...) how did you go through finding the last answer inside ||/var/log||?

simple mountain
#

is that where it says the flag is?

serene badger
#

heyhey

#

im at kenobi task 4 question 2

#

and i dont know what to do

simple mountain
#

The room is a walkthrough room... Which bit?

serene badger
#

never mind i got it'

#

thanks though

clever pivot
#

is that where it says the flag is?
@simple mountain Yes, after getting all user's passwords

simple mountain
#

passwords? are you sure you are in Kenobi room?

#

Oh sorry, mixed you up with the other guy...

#

zthlinux is a big room - Which task are you on?

clever pivot
#

The last one, the little challenge. I finished it already but I want to know how other people went through it, 'cause there is no hint there as where or how to get it, I spent a lot of time to get to it

simple mountain
#

the 'True ending'?

clever pivot
#

Yes

#

The last one, the little challenge. I finished it already but I want to know how other people went through it, 'cause there is no hint there as where or how to get it, I spent a lot of time to get to it
I mean, finding the file is pretty easy, but the challenge gives no hint on how to get it, just throw the challenge at you

simple mountain
#

Oh I see. Thats part of it, and how most other challenges are set out. But HOW to do it is using the skills that have just been taught.

clever pivot
#

Yea, I thought so too, so I tried messing with permissions, shell scripts and such, but in the end I just got lucky I guess 'cause I didn't need any of those

#

In your case, how did you find the ||/var/log/test1234||?

#

And why did you search there for that file?

simple mountain
#

IIRC, I searched for files owned by a certain user.
