C. RST Hijacking This is a form of TCP session hijacking where the attacker sends a forged TCP RST (reset) packet to one or both ends of a connection, spoofing the IP and guessing the sequence/ack number to terminate the connection.

RST hijacking is an attack technique where an attacker injects a forged TCP Reset (RST) packet into an active session. This attack is effective because TCP connections rely on sequence and acknowledgment numbers for maintaining session integrity. In this scenario: - The attacker spoofed the source IP address to match one of the communicating parties. - The attacker guessed the acknowledgment number to make the injected RST packet appear legitimate. - As a result, the victim's connection was forcibly reset and terminated. This aligns precisely with RST hijacking, making it the most appropriate answer.
