Information based AND brute force Password Cracker
This password cracker can crack passwords faster using information about the person who created the password. It also features a brute force password cracker.
It was just a simple program I made to see if I could actually get it working. I guess you could use it to hack accounts. To do that without triggering alarms, you would need to send a request to the webpage attempting to login from the program. Add a buffer in between each request and swap ip addresses and just hope you get in before their account gets locked.
Using that you should be able to hack most simpler websites, but if it were google or something you may lock up their account before you actually get in.
