Overview

People think they are getting smarter by using passphrases. Let's prove them wrong!

This project includes a massive wordlist of phrases (over 20 million) and two hashcat rule files for GPU-based cracking. The rules will create over 1,000 permutations of each phase.

To use this project, you need:

  • The wordlist hosted here.
  • Both hashcat rules here.

WORDLIST LAST UPDATED: July-15-2019

Usage

Generally, you will use with hashcat's -a 0 mode which takes a wordlist and allows rule files. It is important to use the rule files in the correct order, as rule #1 mostly handles capital letters and spaces, and rule #2 deals with permutations.

Here is an example for NTLMv2 hashes: If you use the -O option, watch out for what the maximum password length is set to - it may be too short.

hashcat -a 0 -m 5600 hashes.txt passphrases.txt -r passphrase-rule1.rule -r passphrase-rule2.rule -O -w 3

Sources Used

So far, I've scraped the following:

  • IMDB dataset using the "primaryTitle" column from title.basics.tsv.gz file available here grabbed May 25.
  • From the Wikipedia pages-articles-multistream-index dump generated May-20-2019 here, article titles and category names.
  • From Wiktionary's similar index dump here, the entries generated May-20-2019.
  • Urban Dictionary dataset pulled May 27 2019 using this great script.
  • 15,000 Useful Phrases
  • Song lyrics for Rolling Stone's "top 100" artists using my lyric scraping tool.
  • Meme titles from KnownYourMeme scraped using my tool here on July 15 2019.
  • Movie titles and lines from this Cornell project.
  • Global POI dataset using the 'allCountries' file.
  • Quotables dataset on Kaggle.
  • 1,800 English Phrases
  • 2016 US Presidential Debates dataset on Kaggle.
  • Goodreads Book Reviews from Kaggle. I scraped the titles of over 300,000 books.
  • US & UK top album names, artists, and track names from the 1950s - 2018 using mwkling's tool here.
    • Note: I modified that python script to download multiple charts, as opposed to just US Billboard

Hashcat Rules

The rule files are designed to both "shape" the password and to mutate it. Shaping is based on the idea that human beings follow fairly predictable patterns when choosing a password, such as capitalising the first letter of each word and following the phrase with a number or special character. Mutations are also fairly predictable, such as replacing letters with visually-similar special characters.

Given the phrase take the red pill the first hashcat rule will output the following:

take the red pill
take-the-red-pill
take.the.red.pill
take_the_red_pill
taketheredpill
Take the red pill
TAKE THE RED PILL
tAKE THE RED PILL
Taketheredpill
tAKETHEREDPILL
TAKETHEREDPILL
Take The Red Pill
TakeTheRedPill
Take-The-Red-Pill
Take.The.Red.Pill
Take_The_Red_Pill

Adding in the second hashcat rule makes things get a bit more interesting. That will return a huge list per candidate. Here are a couple examples:

T0KE THE RED PILL

Additional Info

Optionally, some researchers might be interested in:

  • My best-effort to maintain raw sources here.
  • The script I use to clean the raw sources into the wordlist here.

The cleanup script works like this:

$ python3.6 cleanup.py infile.txt outfile.txt
Reading from ./infile.txt: 505 MB
Wrote to ./outfile.txt: 250 MB
Elapsed time: 0:02:53.062531
