Which attack method is being used when an attacker tries to compromise a network with an authentication system that uses only 4-digit numeric passwords and no username?
The attack method being used is a 'dictionary' attack. In this scenario, the attacker exploits the fact that the authentication system only uses 4-digit numeric passwords. A dictionary attack involves using a pre-defined list of possible numeric combinations (0000 to 9999) to attempt to gain access. Since only numeric passwords are used with a fixed length, this type of attack is feasible and straightforward.
