I am practicing cracking MYSQL5 hash using hash cat, however, for a reason or another, it finishes the cracking process too fast -within 30 seconds- without giving any results/errors back.

I doubted that I am using an incorrect hash type, however, I double checked using hash-identifier and other tools as well.

Here is the output:

root@k:~/Desktop# cat hash

root@k:~/Desktop# hashcat -m300 -a0 hash rockyou.txt

I am really confused since I tried hashcat with other hashes and it works fine ! But why it did not work with this one ?

Aside from this, I have seen multiple sites the provide cloud cracking for money. Does anybody have any recommendations/experience with such service ?

Your hashcat appears to be working correctly. 30 seconds is about how long it takes mine to run through every password in rockyou.txt

It looks like the password is not in rockyou.txt which only contains a few hundred thousand passwords.

I suggest you use some rules to make it guess some variations on the passwords in rockyou and/or find a larger dictionary.

d3ad0ne.rule will take a nice long time...

a command might be

hashcat -m 300 -a 0 -r rules/d3ad0ne.rule hash rockyou.txt 
  • Thanks for the response, I will give it a try and let you know how it goes ! – Ahmed Taher May 5 '14 at 16:54
