The Tor Project assures users of network safety amid law enforcement efforts to unmask users using timing attacks. They emphasize protections in place for users of the latest tools but acknowledge the challenges posed by centralized network servers. The organization is frustrated by the lack of court documents but has taken steps to enhance security and address vulnerabilities in tools like Ricochet.
It appears that the Tor Project is facing concerns about the safety of the network following recent reports of law enforcement agencies using timing analysis attacks to deanonymize users. The team behind the specialized web browser has assured users that the latest versions of its tools have adequate protections in place against such attacks. However, concerns have been raised about the control of a large portion of the Tor network’s servers by a small number of entities, which creates an environment where timing attacks are more feasible.
In response to these concerns, the Tor Project has expressed frustration at not being provided access to the court documents that would enable them to validate security-related assumptions. Despite this, they have reassured users that the described attacks occurred between 2019 and 2021 and that significant network growth has made timing attacks much harder to carry out now. Additionally, efforts have been made to flag and remove bad relays, as well as to address centralization within the network.
Regarding the use of an outdated version of Ricochet, the Tor Project has retired that version and replaced it with the next-generation Ricochet-Refresh, which features Vanguards-lite protections against timing and guard discovery attacks.
The Tor Project has also acknowledged the need for greater relay diversity and has called for volunteers to help address this issue, highlighting various initiatives aimed at introducing more bandwidth and variety into the network.
Overall, the Tor Project is working to address the concerns raised and improve the safety and integrity of the Tor network.
