You can also contact the owner of the server if you know who it is and they have a report process, e.g. Cloudflare, Digital Ocean etc.

I feel there is no need for mod involvement when speaking about the legal scope of public testing, when being asked questions about it. We advised on having permission to scan, and staying within the legal scope. As far as I'm concerned this was handled in a professional manner

If someone is admitting to a crime in the discord server, you need to ping a moderator.

Failure to do so will result in you being muted.

It is purely to protect the Discord server. We are already on the radar for being a hacking server, the rules and policies are there to protect both the community members and the Discord server.

Lead by example; if you respond, others will think itโ€™s okay.

It was dealt with because an employee reported it.

It was dealt with before I even finished reading it

the vpn can be hacked yes

night prairie

@rapid merlin Idk if calling them is a good idea xd

rapid merlin

what

#

they cant hack ur pc

#

unless u download

night prairie

perhaps if they had access to the VPN server they could monitor and manipulate traffic

All a VPN does is just shift the trust from your ISP to the VPN provider

well if you want everything to be easy to install endeavour os is shadows go to

as the arch user repository covers a ton of software

eh got out of scope also

sand trench

though it is decently focused on using the terminal to install stuffs

buoyant tree

gonna start looking for CVE's next month

buoyant tree

I was using sudo in windows cmd prompt

#

thats the main reason I am making the switch

sand trench
#

endeavour os is arch based and mint and pop os are ubuntu based which is debian based

#

so slightly different in what package manager you get

#

and what is available in default repos

#

other then that it is mostly the same under the hood

#

yes desktop enviroments that are installed by default or comes with a distro can change the feel a lot but generally you can change that

naive violet

Here's a question for everyone what are your thoughts on the Coursera Cybersecurity program from Google?

buoyant tree
#

Got a question about how hash's work, like if the text is bigger than the hash length then what happens?
Like I know it generates a signature for it but isn't there more things that can be random in a bigger file that the signature is not unique then hash collision happens

glass nest
#

The hash will always be the same length. If could be 1 character or a complete compendium of shakespeares work

sand trench
polar spoke
polar spoke
#

the risk is low enough, however, that it's rarely considered

#

this is the "pigeonhole principle"

sand trench
#

sooo when we getting yescrypt support in hashcat???

#

yes know that will be painfully slow

polar spoke
#

soon, with hashcat 7

#

it won't be that slow

sand trench
#

oh neat

whole yew
shut hawk
#

What size would the input have to be to guarantee a hash collision? ๐Ÿค”

polar spoke
#

doesn't work that way

#

assuming your hashing function is psuedo random and that 1 input will always map to 1 output, where input <= output size, which assumes a normal distribution of mappings

#

then you can also assume that any input > output size will produce a collision with an input that is <= output size

#

finding those, however, is usually as much work as a first preimage iirc

#

hence why it doesn't really matter

whole yew
#

I don't think you can make the assumption that it's a guarantee that exactly 1 input maps to exactly 1 output - just that the likelihood of a collision is m/n where m is the number of recorded inputs and n is the size of the key space

polar spoke
#

also, importantly, hashes are often constructed in such a way that there is always compression from input -> output

polar spoke
#

but for an ideal hashing algorithm, normal/even distribution of the mappings is often assumed

whole yew
#

yeah, i'm not trying to contradict what you said, just clarify for those that do not understand how one way functions are intended to work

polar spoke
#

right, i understood

sand trench
#

one way functions are like how food goes in mouth and come out as poop

polar spoke
#

well, that's one way to put it

whole yew
#

uh. that's a gross reduction of it, shadow

polar spoke
#

I prefer the blender and smoothie tho

sand trench
#

yeah probably quite gross explaination but it should be useable for basically any age group

polar spoke
whole yew
#

i've always had it explained to me mathmatically with respect to set theory and notation

rapid merlin
#

id prefer shadows explanation

whole yew
#

the smoothie idea is more palatable, if you will, but i still prefer the notions of one-to-one and onto

polar spoke
#

I think the concept of trapdoor functions or one way functions in general can be tough to understand

#

even simple ops like modulus

shut hawk
#

But if hash collisions exist then it's a many to one no?

whole yew
#

hash collisions do exist

#

the point of the hash algorithm is to distribute potential inputs across such a sparsely populated keyspace that hte likelihood is extremely low

polar spoke
#

^^

whole yew
#

the likelihood of collision for 2 distinct inputs is 1/n where n is the size of the keyspace

polar spoke
#

and to do so deterministically but with psuedo random outputs

shut hawk
#

You could have a hashing function that didn't have collisions, if the input was a finite amount

sand trench
#

hash collision is like how an orange and a blood orange both create orange juice

Gave +1 Rep to @sand trench (current: #4 - 1630)

whole yew
#

if you have a keyspace of 2^512 bits, then it's a 1/2^512 for any 2 inputs to have a collision

whole yew
rapid merlin

whole yew
#

Then that's a you problem. You can always ask about things you don't understand instead.

rapid merlin
#

right

shut hawk
#

Hmmm okay so hash collisions are so rare it isn't really a risk anyway

polar spoke
#

normally yes

#

but sometimes they do happen

#

and sometimes algorithms are weak

whole yew
#

It's not so much that it isn't a risk

shut hawk
#

Why not just make the possible output length bigger than

whole yew
#

It's a known and quantified risk, and it's accepted that there is some risk, because hashing is only guaranteed to be imperfect

polar spoke
#

but output length is not everything

#

the actual construction of a hash can be weak

whole yew
#

usually you don't do that because it wastes space

polar spoke
#

MD5, for example

#

or SHA1

#

or etc.

whole yew
#

the point of the hash is usually to store a signature, not the original item

shut hawk
polar spoke
#

or generate a key as with KDFs or similar

whole yew
#

so you can verify the authenticity of a claim submitted as the original data

polar spoke
#

MD5 has quite a few known weaknesses

#

some allow you to craft inputs for specific outputs

#

let you cheat your way into collisions

whole yew
#

yeah, those weaknesses are why MD5 is almost always fine for file verification but not for passwords

polar spoke
#

well no

whole yew
#

different risk and different security requirements

polar spoke
#

not anymore

whole yew
#

when did that change?

polar spoke
#

idk, 2004?

sand trench
#

thought so too

polar spoke
#

unless you mean single file, in place

whole yew
#

IIRC as recently as last year most distros were still using MD5 as signatures for repo files

sand trench
#

that md5 should not be used for file checks anymore either

polar spoke
#

oh yeah

#

they shouldnt be

#

they shouldnt have been for like, 20 years

whole yew
#

hmm

polar spoke
#

MD5 checksums aren't worthless but they certainly aren't secure

sand trench
#

sha256 is okay for file checks right???

whole yew
#

the point i think isn't to be secure - just that you can verify authenticity from a known file size and a published signature. Say, for a net-installer or DVD ISO

polar spoke
whole yew
#

i know i've been seeing gpg keys being published for more and more repo files, but i still see a lot of MD5 checksum files as well

polar spoke
#

because altering a file and having it's MD5 stay the same is within reach of adversaries

#

barely, but it's possible

whole yew
#

that would change the original file size though

polar spoke
#

not necessarily

#

MD5 is like, weak weak

whole yew
#

hmmm

shut hawk
#

I presume hashing algorithms are constantly evolving, how long do you think it would be before something like SHA256 is considered unsafe - or no way to tell until somebody finds a weakness in it?

whole yew
#

do you have a case study on it? not doubting, but i need to see the math why

polar spoke
#

in favor of SHA3

sand trench
#

nice that archlinux generally uses gpg to check file integrity after downloading it form repos... and paccheck has sha256 support

polar spoke
shut hawk
#

Oh, never even heard of SHA3

polar spoke
#

as far as free start and chosen prefix goes, Marc Stevens seems to have the most work in that area

whole yew
polar spoke
#

to be clear, changing a file with the MD5 staying the same is barely within reach

#

but changing 2 files to have them collide on MD5 is seconds at most on a modern CPU

#

so someone with control of a benign and a malicious file could alter both to make them have the same MD5 Very easily

#

but altering a file to have a Specific MD5 is much much harder

#

when I say barely in reach, I mean nation states might have the time/resources

whole yew
#

ok, that makes much more sense

polar spoke
#

that's still, imo, a complete break in its security

#

if anyone can do it, it shouldn't be used

sand trench
#

considering how many nation state APT:s there are yeah

whole yew
#

i thought you were saying that the second claim (alter to specific md5) is easy enough to make the algorithm roughly as bad as ROT13

polar spoke
#

no no

#

that's still ~ first preimage levels of hard

#

but that's so easy with MD5 that nation states are within reach

#

which is far far too easy

#

when it comes to crypto, "i think i can in 10 years" means "we should have stopped using it 5 years ago"

whole yew
#

lol, i thought the bounds were a bit tighter

#

like "i think we can break in 5 years" means we should stop using it next year

#

Hashes are commonly used for passwords and to show file integrity

polar spoke
#

as well as to derive fixed length signatures

#

and fixed length keys

#

Hashes can't be "decoded"

buoyant tree
#

hmm pigeonhole principle made some sense

whole yew
#

those fixed length keys are derived for things like diffe-hellman, right?

polar spoke
#

or AES

#

or basically every encryption you can think of that isnt based on two primes or a curve point

mossy river

If you're referring to something like crack station, it doesn't decode them

Mhm

rapid merlin
polar spoke
#

schneiers book is really good

#

touches on lots of stuff

#

might give you the info and vocab to look more things up

mossy river
#

It uses a database, it says at the bottom it's a lookup service

polar spoke
rapid merlin
buoyant tree
#

but is there a more updated version of the book

#

with modern examples

polar spoke
#

honestly, not sure

buoyant tree
#

I know the theory doesn't change

polar spoke
#

crypto doesn't exactly move very fast

buoyant tree
#

but like its 1996

polar spoke
#

AES is, for the most part, still AES

#

and most crypto builds on previous stuff

#

so now, for example, we have AES GCM or XTS, which are based on previous cipher modes but with added features/concepts

sick lance
#

Crypto and Malware are probably two of the more common themes of the old theory is dated but still pretty relevant

polar spoke
#

yeah, crypto is very "learn all the stuff from way back first" imo

mossy river
#

I don't understand

polar spoke
#

jumping straight into salsa20 based stream ciphers mixed with poly1305 without some understanding of the principles/concepts isnt going to get you anywhere

sick lance
#

Probably put you off learning it tbh

polar spoke
#

yuuup

buoyant tree
polar spoke
#

yeah, most anything from schneier is worth reading

whole yew
#

Agreed

#

His books also show up on humble bundle cybersec bundles fairly often

#

IIRC the no starch security bundles have his books regularly

sick lance
#

Yeah, I think that's where I got them.

polar spoke
#

in theory, yes

#

however, that doesn't reduce the security of the hashing algorithm

#

just tells you that that password/value is weak

#

I'm not sure I understand what you mean

buoyant tree
#

time to stop reading harry dresden and start reading studying books

polar spoke
#

yes, that's correct

#

if you find a hash like 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 and look it up, you will quickly find that it's the SHA1 of "password"

shut hawk
#

and there are many tools that do that

polar spoke
#

but that doesn't really mean anything other than that hash is known

#

if you lookup ddb32829d067a05fb0c644e84ef7ac493ab7baf4 you will NOT find the corresponding plaintext anywhere

#

and in fact, you likely couldn't break it even if you tried

#

so really, when you lookup a hash, you are sorta looking up known passwords more than you are looking up known hashes

#

of course, this all relies on the password creating the same hash

#

but modern hashing doesn't really allow that to happen because of the inclusions of salts and varied rounds and peppers and keys and etc.

#

well, i say modern, but really I mean "purpose built" hashing, since bcrypt is from like 1996

buoyant tree
#

and what other books would u recommend chick3nman

polar spoke
#

There's another applied crypto book around that has a similar name that I liked

#

really, "applied cryptography" is the right search term

outside of paid work? going on 10 or so?

#

hmm

#

also does developing hashcat pay?

polar spoke
#

it's hard for me to quantify how long ive been doing this stuff

polar spoke
#

hashcat is a free open source project that doesn't take payment or donations of any kind

#

that said, my experience with hashcat has certainly gotten me paid jobs doing custom development work or security work

buoyant tree
polar spoke
#

indeed

buoyant tree
#

although why is hashcat defined as a password recovery tool exactly

clear jackal
#

And of course now the rest of the conversation loads

buoyant tree
#

not the exact amount

#

since like projectdiscovery the guys that made subfinder, nuclei seem to have jobs to make those things

polar spoke
buoyant tree
polar spoke
#

well, we don't just crack hashes

#

in fact, i'd say the majority of our modes aren't hashes at this point

#

they may involve hashes

#

but they are keys and encryption schemes and such

buoyant tree
#

it seems like a few encryption algorithms also

#

also any plans about recoding hashcat in rust

polar spoke
#

haha

#

hashcat will not be written in rust

#

but future components are already potentially going to include rust, though not for any particular reason other than because some people wanted to

compute is cheaper but also salts kill rainbow tables

and generating rainbow tables is exepnsive compared to just running the computation

searching them can be fast

but only for single hashes

multiple hashes, not so much

you can still buy hdd:s with rainbowtables

In computer networking, IP over Avian Carriers (IPoAC) is a joke proposal to carry Internet Protocol (IP) traffic by birds such as homing pigeons. IP over Avian Carriers was initially described in RFC 1149 issued by the Internet Engineering Task Force, written by D. Waitzman, and released on April 1, 1990. It is one of several April Fools' Day...

RFC 2322

#

Peg DHCP is a method defined in the April Fools' Day RFC RFC 2322 to assign IP addresses in a context where regular DHCP wouldn't work. The "server" hands out wooden clothes-pegs numbered with the addresses to allocate and an additional leaflet with network information. The "client", typically the user, then configures their device accordingly.
