Which hijacking technique masquerades as a trusted host to conceal the attacker’s identity and gain unauthorized access?

• A. IP Address Decoy
• B. Direct TTL Probes
• C. Anonymizers
• D. IP Address Spoofing

Answer: (D)

Masquerading as a trusted host hinges on making the packets look like they’re coming from a valid, trusted machine, so the target system trusts or accepts them. Forging the source IP address achieves exactly that: the attacker sends packets with a spoofed IP, so responses go to the legitimate owner of that IP and the network may treat the traffic as if it came from a trusted source. This helps the attacker slip past access controls that rely on IP identity and can enable unauthorized access or interception. Anonymizers simply hide the real user’s identity by routing traffic through intermediate servers, but they don’t impersonate a specific trusted host within the target network. Direct TTL probes are used for fingerprinting or mapping hosts, not for pretending to be a trusted machine. IP address decoy isn’t a standard hijacking technique in this context.
