So why do WiFi deauth attacks work

It seems like a crazy oversight in the protocol to allow for deauth requests from a non authenticated party, regardless of the mac address it’s pretending to be.

Can someone give me some more insight into this

Cracken : A Fast Password Wordlist Generator, Smartlist Creation And Password Hybrid-Mask Analysis Tool

Cracken is a fast password wordlist generator, Smartlist creation and password hybrid-mask analysis tool written in pure safe Rust (more on talk/). Inspired by great tools like maskprocessor, hashcat, Crunch and  HuggingFace’s tokenizers. What? Why? Woot??

At DeepSec2021 we presented a new method for analysing passwords as Hybrid-Masks exploiting common substrings in passwords by utilizing NLP tokenizers (more info on talk/).

Our method splits a password into its subwords instead of just a characters mask. HelloWorld123!splitted into ['Hello', 'World', '123!']as these three subwords are very common in other passwords. Hybrid Masks & Smartlists

* Smartlists – Compact & representative subword lists created from passwords by utilizing NLP tokenizers
* Hybrid-Mask – A representation of a password as a combination of wordlists & characters (e.g. ?w1?w2?l?d) Analyzing RockYou Passwords with Smartlists & Hybrid-Masks:https://blogger.googleusercontent.com/img/a/AVvXsEhdw7aYM7PSpZpyAxj2u-4S4xa-RtKa2wSJELWr9JAmyn2JAgSWsLl_xYP6-dN2oJGX6JJ286GFvc10yWoTP4uLGiJqBKQ_GwXink27LFP4BQZsNmY6zn_ZSTZdiuz9LjtH2oyKQyAcVq8X-VjvGTXQcIg22DfpSx5afDzr7mrC-ucCdPry8Nfw60CZ=s1236
Cracken  is used for

* https://s.w.org/images/core/emoji/13.1.0/72x72/2705.png Generating Hybrid-Masksvery VERY FAST  (see performance section)
* https://s.w.org/images/core/emoji/13.1.0/72x72/2705.png Building Smartlists– compact & representative list of subwords from given passwords files (using  HuggingFace’s tokenizers)
* https://s.w.org/images/core/emoji/13.1.0/72x72/2705.png Analyzing passwords for their Hybrid-Masks– building statistics for better password candidates (again very fast) Possible workflows with Cracken Simple

1. Generate wordlist candidates from a hybrid mask – e.g. cracken -w rockyou.txt -w 100-most-common.txt '?w1?w2?d?d?d?d?s'2. You can pipe the passwords Cracken generates into hashcat, johnor your favorite password cracker Advanced

1. Create a Smartlist from existing passwords – cracken create2. Analyze a passwords list of plaintext passwords – cracken entropy3. use most frequent Hybrid-Masksto generate password candidates fast – cracken generate -i hybrid-masks.txtFor more details see Usage section

Getting Started

download (linux only currently): latest release

for more installation options see installationsection

run Cracken:

generate all words of length 8 starting with uppercase followed by 6 lowercase chars and then a digit:

$ cracken -o pwdz.lst ‘?u?l?l?l?l?l?l?d’

generate words from two wordlists with year suffix (1000-2999) $ cracken –wordlist firstnames.txt –wordlist lastnames.lst –charset ’12’ ‘?w1?w2?1?d?d?d’

create a Smartlist of size 50k from subwords extracted from rockyou.txt

$ cracken create -f rockyou.txt -m 50000 –smartlist smart.lst

estimate the entropy of hybrid mask of the password HelloWorld123! using a smartlist

$ cracken entropy -f smart.lst ‘HelloWorld123!’
hybrid-min-split: [“hello”, “world1”, “2”, “3”, “!”]
hybrid-mask: ?w1?w1?d?d?s
hybrid-min-entropy: 42.73
charset-mask: ?l?l?l?l?l?l?l?l?l?l?d?d?d?s
charset-mask-entropy: 61.97

Performance

As of writing this, Cracken is probably the world’s fastest wordlist generator:

Cracken has around 25% increased performance over hashcat’s fast maskprocessor thats written in C.

Cracken can generate around 2 GB/s per core.

more details on benchmarks

Why speed is important? A typical GPU can test billions passwords per second depending on the password hash function. When the wordlist generato[...]

r produces fewer words per second than the cracking tool can handle – the cracking speed will degrade. Hybrid-Masks Analysis Performance

Cracken uses A*algorithm to analyze passwords very fast. it can find the minimal Hybrid-Mask of passwords file at rate of ~100k Passwords/sec (cracken entropy -f words1.txt -f words2.txt ... -p pwds.txt) Installation

install Cracken or compile from source Download Binary (Linux Only Currently)

download latest release from releases Build From Source (All Platforms)

Cracken is written in Rust and needs rustc to get compiled. Cracken should support all Platforms that Rust support.

installation instructions for cargo there are two options building from source – installing with cargo from crates.io (preferred) or compiling manually from source.

install from crates.io (preferred)

install with cargo

$ cargo install cracken

build from source

clone Cracken:

$ git clone https://github.com/shmuelamar/cracken

build Cracken:

$ cd cracken
$ cargo build –release

run it:

$ ./target/release/cracken –help
