ASLR works by taking code and shifting the memory location in which it runs. It is an alternative to the use of address space layout randomization (ASLR), which Tor had used previously. The Tor Project and researchers from the University of California, Irvine have been collaborating to create Selfrando. The article described this feature as “an enhanced and practical load-time randomization technique.” This should prevent user identities from ever going public as the result of a cyberattack. A New Way to Randomize Memoryīut there’s more: Softpedia reported that this hardened version of the Tor browser includes a new feature called Selfrando. This hardening was needed given recent and apparently successful deanonymization attacks, which revealed the identities of Tor users. The Project worked on the Firefox browser that runs underneath Tor to reduce its potential as an attack surface. Hardening the Tor BrowserĪs the Tor Project announced on its blog, the latest version of its browser “updates Firefox to 45.2.0esr and contains all the improvements that went into Tor Browser 6.0.” Specifically, this new release boasts significant security advancements designed to avoid privacy invasions and deanonymization - things Tor is supposed to fundamentally prevent. The Onion Router (Tor) released version 6.5a1 of its browser in early June, and users will be happy to note that the updated browser contained some welcome security initiatives.
