Which statement about Hashcat's handling of usernames and GECOS fields is accurate?

• A. Hashcat uses usernames to personalize password guesses.
• B. Hashcat uses GECOS fields to determine password complexity.
• C. Hashcat does not utilize usernames and GECOS fields to formulate its guesses.
• D. Hashcat relies on the machine hostname to seed guesses.

Answer: (C)

Hashcat builds its candidate passwords strictly from what you provide: wordlists, rules, and masks. It does not automatically pull in usernames or GECOS fields from the target system to influence its guesses. If you want those data points to affect cracking, you must include them yourself in your wordlists or apply rules that transform those strings into candidates. The machine’s hostname isn’t used to seed guesses by default either; any such data would need to be added to your inputs manually. So the statement that Hashcat does not utilize usernames and GECOS fields to formulate its guesses is accurate.
