Researchers find more than 100 Tor nodes that are snooping on users
Extreme Tech - 07/27/2016
Security researchers (and indeed, law enforcement) have worked out a number of theoretical ways to attack Tor. This might involve taking over a significant number of nodes, which are just computers and servers around the world, to crack anonymity. Or it may involve simply monitoring the time that connections enter and exit Tor as a way to correlate the anonymized endpoint with a known starting location. The issue spotted by Amirali Sanatinia and Guevara Noubir from Northeastern University seems to be a more modest kind of snooping, but there’s plenty of it going on.
