Which of the following tools automates password guessing in the NetBIOS session?

L0phtCrack is an offline Windows password auditing tool that recovers credentials by cracking NTLM and LM password hashes, not by automating live authentication attempts against NetBIOS sessions.

John the Ripper is a general-purpose offline password hash cracker that operates against stored hash files, not against live NetBIOS session authentication.

Legion is a network scanner and brute-force utility that specifically targets NetBIOS sessions, automatically attempting to authenticate to Windows file shares and other NetBIOS-based services using dictionary or brute-force methods. It can sweep IP ranges, enumerate NetBIOS shares, and systematically guess credentials without manual intervention. This direct focus on automating NetBIOS session password attacks distinguishes it from the other tools listed.

NTInfoScan is a Windows network enumeration and information-gathering tool used to collect system and share details, not to perform automated password guessing against NetBIOS sessions.
