Has anyone come across any good password dictionary lately? Some of the lists I found dated back to 90's! Some are simply too big that I doubt their quality. There appears to be some work by someone for a paid list though at http://dazzlepod.com/uniqpass/ but I am looking for something hopefully free!
As the old adage says, "it's not the size of your word list that matters, it's how you use it." And which you use. I will provide you with some tips.
For password lists and non-password word lists relevant to my suggestions, see SkullSecurity, KoreLogic, and Openwall. The leaks mentioned are all from SkullSecurity. Or you can hunt down leaks and use them as a basis, over time developing good lists. See the twitter feeds of pastebinleaks and keep an eye on the news and hunt down leaks that are announced, especially when in plaintext. Even if some of the leaks are pure hashes and you need to crack them, it will still give you an idea of what is being used in the wild and help you assess the value of your password lists.
On to the advice.
- Chose a word list relevant to your target's user base
- Password leaks similar to your target (e.g. Faithwriters, Hak5, Ultimate Strip Club List)
- Relevant topics (Sport teams and terminology, slang, city/town names)
- Relevant languages (e.g. Älypää leak, foreign dictionaries, foreign Wikipedia)
- Generate your own!
- Crawl target's website
- Strip and then use mangling rules on passwords already cracked
- Look for trends in passwords already cracked and find a source (or generate one) that is categorically similar
- Mangle generic lists
- Look at JtR's default mangling rules and KoreLogic's published ones for inspiration
- Name lists. first initial last name, first name last initial, first name, last name
- Write mangling rules that fit patterns you see in passwords already cracked
- Lists of random ordinary stuff (e.g. phone numbers)
- Don't use lists at all
- Markov chains (see JtR Jumbo)
- JtR default incremental modes
- Other probability stuff
- Go through all digit combinations between 1 digit and as high as you can handle
- Use Rainbow tables if unsalted passwords are in use
- Be lazy and use generalized leaks like RockYou
- Think about password policy
- EXCLUDE GUESSES OUTSIDE PASSWORD POLICY
- Learn what the password policy is through analysis on cracked passwords
- Realize patterns may just be your imagination or created by your tactics
- Think about what keyspaces and tactics you haven't tried
- Password lists aren't everything
- Learn to write good mangling rules
- Analyze what you've cracked
- Use scripting to generate common patterns on-the-fly
- Create your own word lists
- Chose relevant lists
The best site I found for this is SkullSecurity. It does have huge collection of passwords. Some were leaked during real attacks, so they are pretty recent.
I just found a good looking source:
just use "fgrep" for various passwords in the dictionary to test the quality. The top passwords are at the beginning of it (for slow hashes I assume).
Looks like many things got into this wordlist that has 3 001 834 125 lines, 40 GBytes. Compressed: 6.5 Gbytes.
I came across this page http://cyberwarzone.com/cyberwarfare/password-cracking-mega-collection-password-cracking-word-lists recently. There's links to a large number of lists there, so hopefully some useful ones.
