Tor network statistics11/11/2023 Grouping these servers under the KAX17 umbrella, Nusenu says this threat actor has constantly added servers with no contact details to the Tor network in industrial quantities, operating servers in the realm of hundreds at any given point. KAX17: Non-amateur level and persistent groupīut a security researcher and Tor node operator going by Nusenu told The Record this week that it observed a pattern in some of these Tor relays with no contact information, which he first noticed in 2019 and has eventually traced back as far as 2017. However, despite this rule, servers with no contact information are often added to the Tor network, which is not strictly policed, mainly to ensure there’s always a sufficiently large number of nodes to bounce and hide user traffic. Servers added to the Tor network typically must have contact information included in their setup, such as an email address, so Tor network administrators and law enforcement can contact server operators in the case of a misconfiguration or file an abuse report. Their role is to encrypt and anonymize user traffic as it enters and leaves the Tor network, creating a giant mesh of proxy servers that bounce connections between each other and provide the much-needed privacy that Tor users come for. Some of these servers work as entry points (guards), others as middle relays, and others as exit points from the Tor network. Tracked as KAX17, the threat actor ran at its peak more than 900 malicious servers part of the Tor network, which typically tends to hover around a daily total of up to 9,000-10,000. Since at least 2017, a mysterious threat actor has run thousands of malicious servers in entry, middle, and exit positions of the Tor network in what a security researcher has described as an attempt to deanonymize Tor users.
