This blog post is a response to an investigative news report about a large-scale law-enforcement attack that managed to de-anonymize a user of an old version of the long-retired app Ricochet. This blog post aims to provide insight into what we know so far. Nothing that the Tor Project has learned about this incident suggests that Tor Browser was attacked or exploited. Tor users can continue to use Tor Browser to access the web securely and anonymously.
As we bid farewell to 2023, we reflect on the hard work of the Tor Project's teams and their many noteworthy achievements to improve Tor and its experience for millions of users all around the world. Thank you to our community of users, volunteers, relay operators, partners, and donors for making these projects possible through their generous contributions.
In this blog post, we want to reaffirm our commitment to keeping Tor free and provide insight into the rationale behind the recent removal of certain bad relays.
Today, we are officially introducing a proof-of-work (PoW) defense for onion services designed to prioritize verified network traffic as a deterrent against denial of service (DoS) attacks with the release of Tor 0.4.8.
Why Tor is slow right now and what we are doing about it.
Tor Project is participating once again in Google Summer of Code in 2022. Starting in June we will have two OONI projects and one project for helping the Tor's network health.
Tor has released 0.4.7.7, the first stable Tor release with support for congestion control. Congestion control will result in significant performance improvements in Tor, once Exit relays upgrade. Relay operators: please read!
In this post, we'll explain what we do to fight malicious relays in our network, how we did in the past, and what further improvements are upcoming and being worked on.
With the deprecation of V2 onion services right around the corner, it is a good time to talk about V3 onion services. This post will discuss the most important privacy improvements provided by V3 onion services as well as their limitations. Aware of those limitations, our research group at the Institute of Network and Security at JKU Linz conducted an experiment that extracts information about how V3 onion services are being used from the Tor network.
In our last article, published in RIPE's website, we described the work that happened in 2020 related to giving IPv6 support to the Tor network. Tor 0.4.5.1-alpha is the first release that includes all the work described in the RIPE article. Relays running 0.4.5.1-alpha are the first to report IPv6 bandwidth statistics.
