What type of attack is indicated by multiple failed logins with variations of the same password?

The scenario described involves multiple failed logins using variations of the same password, which indicates a dictionary attack. In a dictionary attack, an attacker systematically attempts a list of predefined passwords or password variations based on common terms, phrases, or even slight modifications of known passwords. This approach leverages the understanding that users often choose weak or common passwords, making it easier for attackers to gain unauthorized access.

In this case, the variations of the same password suggest that the attacker is using knowledge of likely passwords or variations thereof to try to gain access, characteristic of a dictionary attack strategy. This method contrasts with other types of attacks, such as brute-force attacks, which involve trying all possible combinations without leveraging any knowledge of likely passwords.

By recognizing the pattern of sustained attempts with slight modifications, it's clear that the attacker is using a targeted approach typical of dictionary attacks rather than broad, more random efforts seen in other methods.
