Forensic Investigator Patel is analyzing network traffic related to a cyber-attack. The traffic was routed through the Tor network, making it…

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.

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.

and the associated "Tips for Running an Exit Node" section details the potential for abuse complaints directed at the exit relay operator.
