"WebA dictionary attack is a basic form of brute force hacking in which the attacker selects a target, then tests possible passwords against that individual’s username. The attack method itself is not technically considered a brute force attack, but it can play an important role in a bad actor’s password-cracking process. " - Cryptanalysis attack definition
