How to bruteforce?

[mormaii2]

Hey guys, i'd like to know how can i bruteforce using oclHashcat plus since i've already tried using a dictionary which is 5GB (30.000.000.000 words) and i only cracked 2 out of 7 hashes.

i've been using this syntax

cudaHashcat-64.exe -m 15 -o D:\finished.txt -r rules/best64.rule D:\hashlist.txt D:\dictionary.txt

So seeing as cracking with dictionary didn't work i'd like to know how to do it with bruteforce. Thank you!

There was already a topic about that. I'll write it up again.

You can pipe the maskprocessor's output to oclhashcat-plus.
E.G.:

Code:

maskprocessor.exe -1 ?l?u?d?s ?1?1?1?1 | ./oclhashcat-plus64.exe -m 15 -o D:\finished.txt -r rules/best64.rule D:\hashlist.txt

This will bruteforce all lowercase (?l), uppercase (?u), digits (?d) and specials chars (?s) on a length 4.

That beeing said, I suggest NOT to bruteforce salted hashes. Especially when there is many of them. In your case i understand you have 5 hashes left : It is still a bad idea to bruteforce those but it is up to you.

one more thing: there's no point having a 5Gb dictionary full of crap(*)... You better use more (or differents) rules. best64.rule is good for a quick run and slow algos such as FreeBSD MD5, etc.
For example: the new T0XlC.rule set is really cool, try it on rockyou.txt or any other good dictionaries.

well my 5GB dictionary is made up of the best dictionaries there are. Rockyou,phpbb,insidepro's,etc... Well then i'll try my dictionary with the T0XIC rule, any other advice?

With the T0XIC rule it will take 2 days to run through the whole dictionary XD i'll try T0XIC with rockyou only.
