Recovery not even starting - cube - 03-20-2015
So, I just started using oclHashcat and after my first test passed, and worked (just a simple md5 masked attack against password "hello"), the next ones don't even start.
Or rather, it says it started, and immediatelly stops. Here's the output: (yes, I did modify exec timeout in the registry)
edit: The password I'm testing for now is "aaa".
Code:
D:\Pentesting\PasswordCracking\cudaHashcat-1.33>cudaHashcat64.exe -a 3 -m 0 aab.

First of all, according to the forum rules you are not allowed to post hashes see https://hashcat.net/forum/announcement-2.html
Second, the hash that you use corresponds to a password with 4 characters "aaa\n" where \n represents a new line.
The masked/obfuscated hash for "aaa" (without new line) is 47bXXXc74XX89f48XXXXd5XX9cXXX808
oclHashcat doesn't crack passwords of length 4 if you give it a 3 character long mask.

Sorry, didn't think about it(rules), but thank you for the tip, really didn't realize that I added a new line to my hash, propably typical newbie error. Thank you for the fast response.
