Abstract :	[en] Tor is a widely used anonymity network providing low-latency communication capabilities. The anonymity provided by Tor heavily relies on the hardness of linking a user’s entry and exit nodes. If an attacker gains access to the topological information about the Tor network instead of having to consider the network as a fully connected graph, this anonymity may be reduced. In fact, we have found ways to probe the connectivity of a Tor relay. We demonstrate how the resulting leakage of the Tor network topology can be used in attacks which trace back a user from an exit relay to a small set of potential entry nodes.
