Ok this is a different technique to cracking accounts rather than mass combo checking this is where we seek out a certain site and we seek out a certain username / account.
Ok so some things we will use are
sift tool (to search through combos)
first you unzip sift and you put it into the same directory as your combos. If you don't already, your combo lists should all be in a seperate folder. If not well then it's time to get organized.
Put all of your combos in the same folder. Then put the sift.exe and other lic file into the same folder as your combos.
Switch to that directory
On windows its command prompt cd c:/users/yourname/desktop/combos/
or wherever your combos folder is.
ok after you switch to that direcory you use sift like this
SO this command will search in our combos folder for any occurance of "username"
So of course instead of "username" you would be searching for any account you want on any site. I have cracked many sites this way including nethingoez, cracking-italy, imsoldiers, blackhatsem imseo, cboxera, and any other site that lists the usernames of premium accounts.
So the more combos you have in your folder the better off you will be. Good luck have a good day cracking shit.
