What is a dictionary attack?

A dictionary attack is a type of cyber attack where an attacker systematically tries to gain unauthorized access to a target system or account by using a pre-compiled list of commonly used passwords or phrases. The attacker uses automated software to rapidly input these passwords or phrases until a match is found, allowing them to gain access to the system or account. This attack relies on the fact that many users tend to use weak or easily guessable passwords, making it easier for the attacker to guess the correct password and gain unauthorized access.
