Tor обновил систему обхода блокировок

Анонимайзер The Tor Project обновил свой одноимённый браузер с целью устранения проблем, связанных с обходом доступа к определённым сайтам. По словам разработчиков, был использован алгоритм, позволяющий с высокой точностью наладить систему шифрования веб-адресов. Для обхода блокировки сайтов теперь была использована новая технология. После того, как в России расширили список сайтов, доступ к которым россиянам ограничен, The Tor Project решил усилить систему обхода блокировок.

Анонимайзер позволяет на высокой скорости заходить на сайты, а создание популярными брендами официальных странице в сервисе Tor свидетельствует о популярности и надежности анонимайзера.


Tor Browser 7.0.9 is released

Note: Tor Browser 7.0.9 is a security bugfix release for macOS and Linux users only. Users on Windows are not affected and stay on Tor Browser 7.0.8.
Tor Browser 7.0.9 is now available for our macOS and Linux users from the Tor Browser Project page and also from our distribution directory.

This release features an important security update to Tor Browser for macOS and Linux users. Due to a Firefox bug in handling file:// URLs it is possible on both systems that users leak their IP address (note: as of Nov. 4, 2017, this link is non-public while Mozilla works on a fix for Firefox). Once an affected user navigates to a specially crafted URL the operating system may directly connect to the remote host, bypassing Tor Browser. Tails users and users of our sandboxed-tor-browser are unaffected, though.

The bug got reported to us on Thursday, October 26, by Filippo Cavallarin. We created a workaround with the help of Mozilla engineers on the next day which, alas, fixed the leak only partially. We developed an additional fix on Tuesday, October 31, plugging all known holes. We are not aware of this vulnerability being exploited in the wild. Thanks to everyone who helped during this process!

We are currently preparing updated macOS and Linux bundles for our alpha series which will be tentatively available on Monday, November 6. Meanwhile macOS and Linux users on that series are strongly encouraged to use the stable bundles or one of the above mentioned tools that are not affected by the underlying problem.
Update: Tor Browser 7.5a7 has now been released.

Known issues: The fix we deployed is just a workaround stopping the leak. As a result of that navigating file:// URLs in the browser might not work as expected anymore. In particular entering file:// URLs in the URL bar and clicking on resulting links is broken. Opening those in a new tab or new window does not work either. A workaround for those issues is dragging the link into the URL bar or on a tab instead. We track this follow-up regression in bug 24136.
