Hi all,

wrote some shitcode for mysql user&hash enumeration when having FILE 
privilege. surely you could do it with simple bash one-liner using 
mysql+grep+sed, but we're not going the easy way, right?

the first thought was "hey, what about changing root password directly 
in file user.MYD?" but then...

anyway we have Nvidia cards and Hashcat.

Cheers,

Kai
