My colleagues and I published a (not yet peer-reviewed) research paper
on how DNS affects Tor's anonymity. The key parts of our work are:
- We measure the DNS setup of exit relays over time, showing that at
times Google got to see almost 40% of DNS requests coming out of Tor.
- We show how website fingerprinting attacks can be augmented with
observed DNS requests, resulting in precise attacks for unpopular
- Similar to the "Users Get Routed" work, we simulate the impact of our
attack at Internet-scale using the TorPS simulator.
