A security analyst is investigating a potential network-level session hijacking incident. During the investigation, the analyst finds that the attacker has been using a technique in which they…

Blind hijacking refers to a scenario where the attacker can inject data into a session but cannot see the responses from the target, which is not the primary technique described here.

UDP hijacking is not applicable because UDP is a connectionless protocol and does not utilize RST packets to terminate sessions.

RST hijacking involves an attacker injecting a spoofed TCP RST (reset) packet into an existing TCP connection. By correctly guessing the acknowledgment number and spoofing the source IP and port, the attacker can cause the legitimate endpoints to prematurely terminate the session, effectively hijacking or disrupting it.

TCP/IP hijacking is a broad category of attacks that includes various methods; RST hijacking is a more specific and accurate term for the technique described, which explicitly involves RST packets.
