ExoneraTor checks whether a given IP address was a Tor relay node on a specific date, helping distinguish Tor exit traffic from direct connections.

Investigator Use

Tor IP Relay (Tor Exonerator) is an official service provided by the Tor Project at exonerator.torproject.org that allows investigators and system administrators to determine whether a specific IP address was operating as a Tor exit node, relay, or bridge at a specific date and time in the past.


For OSINT investigators and law enforcement, the Tor Exonerator solves a critical problem in Tor-related investigations: when a suspicious or malicious connection originates from an IP address, it is essential to know whether that IP was a Tor exit node at the time of the connection. If it was, the actual originating user could be anywhere in the world — the exit node IP is the last Tor relay, not the user's real IP address.


Primary investigative use: When analyzing logs from a compromised system, threat intelligence platform, or abuse report, run suspicious IP addresses through Tor Exonerator with the relevant date and time. If the IP is confirmed as a Tor exit node at that time, the investigation must account for the Tor anonymization layer and cannot attribute the connection to the IP address owner.


This determination is also critical for exonerating individuals whose IP addresses appear in connection logs due to running Tor relays. A Tor relay operator whose IP appears in a criminal access log may simply have been operating a legitimate Tor node — Tor Exonerator confirms this distinction.


For threat intelligence work, Tor Exonerator helps categorize suspicious connections. Organizations experiencing repeated attacks from Tor exit nodes can use this context to understand the attacker's likely use of anonymization infrastructure and adjust their defensive posture accordingly.


The service queries the historical Tor consensus data maintained by the Tor Project, which records relay and exit node status at each consensus period. Results include whether the IP was listed as a relay, exit, or guard node and the relevant time period.


Record all Tor Exonerator query results with the IP address queried, date and time range, and the exact result returned for inclusion in investigation documentation.
