Researchers have discovered over 100 malicious nodes on the Tor anonymity network that are "misbehaving" and potentially spying on Dark Web sites that use Tor to mask the identities of their operators.
Two researchers, Amirali Sanatinia and Guevara Noubir, from Northwestern University, carried out an experiment on the Tor Network for 72 days and discovered at least 110 malicious Tor Hidden Services Directories (HSDirs) on the network.
The nodes, also known as the Tor hidden services directories (HSDirs) are servers that act as introductory points and are configured to receive traffic and direct users to hidden services (".onion" addresses).
