As a security administrator, you have been noticing an unusual amount of login failures occurring every night on a company server between 2:00 AM and 3:00 AM. Analyzing the logs, you recognize that the login attempts are being made on many user accounts with different common passwords. Each affected user account only has 1-2 attempts before a new account is used by the attacker. What type of password attack is most likely being carried out?
Credential stuffing
Password spraying
