    A group of researchers from Princeton University, Karlstad University and KTH Royal Institute of Technology have devised two new correlation attacks that can be leveraged to deanonymize Tor users. Collectively dubbed DefecTor, the attacks improve the efficacy of existing website fingerprinting attacks through the attacker’s ability to observe DNS traffic from Tor exit relays. The attacks offer great-to-perfect results – the latter mostly when identifying visitors to infrequently visited sites. “It is well understood that … More →
