Tor Relay Operators in End-to-End Correlation Position

The following table lists relay operators that are in a position to see a tor client’s entry and exit connections. In the worst-case a tor client would use these groups as entry (guard) and exit relay at the same time.

Operators are only listed if they actually have a chance to do end-to-end correlation attacks, that is:

This list might contain false-positives as ContactInfo is not authenticated.

The ContactInfo is truncated. Middle-only relays are not included in per-group relaycounts.

The table is sorted by guard probability.

For a detailed list of (known) relays in end-to-end correlation position see this page.

NOTE: There are many more relays with MyFamily configuration issues but most operate exit or guard relays exclusively or within a single /16 network block. Such operators can not become the first and last hop of your tor circuits, but they might be able to reveal your guard relay (when they act as the middle and exit relay in a single circuit).

Biggest Relay Families on the Tor Network

Relays are aggregated based on effective families. Effective families are relays with a mutually configured MyFamily setting. Single relays (without family) are also considered but not aggregated. The first column usually shows the contact information, or if no contact information was provided, the first 8 characters of the relay fingerprint.
