Crack people's passwords with rules (hashcat & john)

Check out my wordlist project at: https://github.com/clem9669/wordlists

I use hashcat (https://github.com/hashcat/hashcat/). Rule are supposed to be compatible for john and hashcat or others.

3 rules exists to adapt to hashing algorithm speed. Large for fast hash algorithms like MD5/NTLM/MySQL3. Small for slow hash algorithms like bcrypt.

This was for basic coverage of passwords for non-educated people who only add 1 letter, 1 digit, 1 punctuation, 1 digit+punctuation, 2 digits+punctuation or a year or some other famous tricks (ex: p@$$w0rd) to their password.

📣 Update: I have extended these rules to be more than just that. 📣

I have removed casing in Large & Medium. Please run as: -r toggle-case.rule -r clem9669_big.rule

The Big rule is :

• clem9669 medium list
• mp64 (https://hashcat.net/wiki/doku.php?id=maskprocessor)
• One Rule to Rule Them All
• InsidePro-PasswordsPro
• InsidePro-HashManager
• Fordy50K

The medium is mine.

The small is only adding 1 character (start & end) with toogle cases. Its purpose is to be combined with others rules as: -r clem9669_big.rule -r clem9669_small.rule or to be used as is with low rate cracking algorithms.

$ wc -l *.rule
      19 clem9669_case.rule
 4091517 clem9669_large.rule
  179552 clem9669_medium.rule
     386 clem9669_small.rule
    5715 emojis.rule
 4277189 total

This is the only thing you need to write your rules : https://hashcat.net/wiki/doku.php?id=rule_based_attack

I recommend using clem9669_small as a reference to start understanding how to write rules.

There are already some really good rules out there but best64 is too small and bigger ones might be too big with too many random things when targeting a certain language like french.

• https://github.com/NotSoSecure/password_cracking_rules, is good but does many random things

• https://github.com/praetorian-code/Hob0Rules, too many random rules

• https://github.com/NSAKEY/nsa-rules, idem

I wanted to make my own and I feel better using mine now. My rules are not random rules in clem9669_medium.

Moreover getting your hands dirty gives you a better understanding of what you're doing.

This becomes handy especially in combination with the rules generator but also for statistical analysis of your rule sets.

To save any rule that generated a matched password, use these switches:

--debug-mode=4 --debug-file=matched.rule

This will save the matched rule on every match, so the resulting rule file might contain many duplicate rules.

At high rates of cracking per second, this may slow down cracking a little bit. At lower rates of cracking per second, the impact is probably negligible.

With hashcat we can debug our rules easily. This means we can verify that the rule we wrote actually does what we want it to do. All you need to use is the --stdout switch and omit the hashlist.

hashcat -r clem9669_large.rule --stdout password
