Researchers have discovered at least 110 nodes on the Tor network that are “misbehaving” and potentially spying on service activity.Over 72 days, computer science PhD student Amirali Sanatinia and Guevara Noubir, professor at the College of Computer and Information Science at Northeastern University uncovered nodes on the network which were not behaving as they ought.
The nodes, otherwise known as Tor Hidden Services Directories (HSDirs), servers which receive traffic and directs users to hidden services, are a crucial element needed to mask the true IP of users on the network.
