Forensic Investigator Patel is analyzing network traffic related to a cyber-attack. The traffic was routed through the Tor network, making it challenging to trace the origin of malicious activities. During the investigation, Patel identifies suspicious traffic leaving the Tor network through a specific relay. In the investigation, which type of Tor relay is most likely to face legal scrutiny and complaints due to its visibility to destination servers, even if it is not the origin of malicious traffic?
Answer options
A: Exit Relay Correct answer
B: Entry Relay
C: Transfer Relay
D: Middle Relay
Correct Answer:
A. Exit Relay
Explanation

The exit relay is the final node in a Tor circuit through which traffic passes before reaching its final destination. The destination server (e.g., a website) sees the IP address of the exit relay as the source of the traffic. Consequently, if the traffic is malicious, any complaints, legal notices, or blocklisting actions are directed at the operator of the exit relay, making it the most legally exposed component of the Tor network.

Why Incorrect

B. Entry Relay: The entry relay (or guard relay) only sees the user's real IP address but not the final destination; it is not visible to the destination server.
C. Transfer Relay: This is not a standard term in Tor architecture. Relays are typically categorized as entry (guard), middle, or exit.
D. Middle Relay: A middle relay passes traffic between the entry and exit relays. It does not know the user's IP or the final destination, providing a crucial layer of anonymity.
