摸進俄羅斯的外包廠商,意外發現的專案:降低 Tor 匿名性的工具

俄羅斯政府的外包廠商 SyTech 被摸進去後,被發現裡面有些「有趣」的軟體:「Hackers breach FSB contractor, expose Tor deanonymization project and more」。

這次被放在標題的軟體叫做 Nautilus-S,透過被加過料的 Tor server 與 ISP traffic 交叉分析,試著找出俄羅斯內的 Tor 使用者:

Nautilus-S - a project for deanonymizing Tor traffic with the help of rogue Tor servers.

這不是新東西,之前就有被提出來,但並沒有這次直接給整包軟體出來:

The first was Nautilus-S, the one for deanonymizing Tor traffic. BBC Russia pointed out that work on Nautilus-S started in 2012. Two years later, in 2014, academics from Karlstad University in Sweden, published a paper detailing the use of hostile Tor exit nodes that were attempting to decrypt Tor traffic.

而且看起來有不少節點正在運行:

Researchers identified 25 malicious servers, 18 of which were located in Russia, and running Tor version 0.2.2.37, the same one detailed in the leaked files.

不知道 Tor 會不會有行動...
