Rules hashcat - ksp - 10-03-2010 First of all, what a nice tool hashcat is! Even on my slow hardware it by far the fastest cracker I've tried. So now when I tried it out for a couple of days I want to know more about rules. I've so far used the gui, but since I'm more of a console guy I'll switch to the command line any minute. Let's say I want to Captialize the first tocken and append a year e.g winter -> Winter2010 I know how to fix the append a year ($2$0$1$0) but how to capitalize the first char? Is hashcat rules compatible with oclHashcat? Is there any howto or guide how to build your own rules? I think that custom rules (with hashcat) can be one of the most efficient way to crack stubburn hashes. RE: Rules hashcat - Rolf - 10-03-2010 Note, hashcat's rule engine is compatible to PasswordsPro's and JtR's(excluding preprocessing). Oh, and it also has a very nifty "generate N rules" feature. RE: Rules hashcat - D3ad0ne - 10-03-2010 hashcat and oclhashcat both uses rules very similar to JTR - http://www.openwall.com/john/doc/RULES.shtml For hashcat to capitalize the first letter use the rule "c" without the quotes in a single line of a rule file. You are correct about the "$2$0$1$0" to append 2010 to the end of the dictionary word. I prefer using oclhashcat to do a single simple rule such as: - oclhashcat64.bin -m0 -n80 -j c -k \$2\$0\$1\$0 hash.list dict.dic dict.dic The above example will use merge words from the same dict.dic capitalizing the first letter and appending 2010 to the end. Remember to use a \ to negate the $ on the command line(linux). However if you want to just use a simple dictionary it would be: - oclhashcat64.bin -m0 -n80 -j c -hash.list dict.dic 2010 I think a better example would be just to brute the last 4 characters with every digit to cover a wider range: - oclhashcat64.bin -m0 -n80 -j c -hash.list dict.dic ?d?d?d?d I compiled a list of frequent rules in order of occurrence and can be used as a rule file in hashcat, or they can be used to give use some ideas to use in oclhashcat - http://hashcat.net/misc/D3ad0ne_long.rule RE: Rules hashcat - ksp - 10-03-2010 Ahh, ok. Well then I'll just try out some JtR rules ;-) How does "generate N rules" works? I see the option in the gui but how does it make it's rules? Are they based on cracked passwd? I really wish there was more documentation in making rules. Maybe there is, but in that case I missed it. Anyway, thanks for your quick reply //KSP RE: Rules hashcat - D3ad0ne - 10-03-2010 Rules are not exactly like JTR but pretty close. To use the -g option in hashcat it just randomly generates rules. You can generate as many random rules as you want. RE: Rules hashcat - ksp - 10-03-2010 Ohh, another quick reply, thank you D3ad0ne! Well, now I have everything I need to read about rules. Your 10 000 rules-file is a gold-mine of rules So the rule c$2$0$1$0 capitilaze and append 2010? Well,I'm off for reading everything about rules (and save money to get me a couples of Nvidia's) //KSP RE: Rules hashcat - D3ad0ne - 10-03-2010 Yes that is how it should work |
