Download Abstract
We present a moderately simple to implement but
very effective and silent deanonymization scheme for Tor traffic. This is done by bridging the mixes in Tor, that is, we control both the traffic leaving the Onion Proxy (OP) and the traffic entering the Exit node. Specifically, from a user’s viewpoint, our proposal has been implemented in the popular Android platform as a spyware, having the dual aim to manipulate user traffic before it enters the Tor overlay and explicitly instruct OP to choose an exit node that is controlled by the attacker. When the user traffic is received by the rogue exit node it is filtered, and the sender’s IP details become visible. Notably, apart from deobfuscating normal http traffic, say, send via the Tor browser, the proposed scheme is able to manipulate https requests as well.
