Password Cracking
Despite the depictions seen in movies, TV shows, and other media, password cracking isn’t as simple as a hacker sitting in front of a computer running some software that immediately returns a list of cracked passwords. Indeed, this process is much more involved. Password cracking can basically take one of four forms, all of which are designed to obtain a password that the attacker is not authorized to possess. An attacker can basically use four password cracking methods:
-
Passive online attacks
-
Active online attacks
-
Offline attacks
-
Nontechnical attacks
Each of these attacks offers a way of obtaining a password from an unsuspecting party in a different but effective way.
