There are no exit relays when using hidden services
- kevin_thibedeau 3y agoIf they're running the hidden service or have a backdoor it's just as compromised.
- ryeights 3y agoYes… but that’s a much bigger ‘if’
- kevin_thibedeau 3y agoThe widespread adoption of TLS means that a far greater effort has been put into exploits needed to gain access to the unencrypted side of a communication channel. It's not as big an if as it was before Snowden.
- voldacar 3y agoThey can just do traffic correlation.
- ryeights 3y agoCorrelation attacks only work when you can see both ends of the traffic. When you visit an .onion address, there is no other “end”—all traffic stays within the Tor network and goes directly to the hidden service server, which is ‘just’ another relay within the network.
- voldacar 3y agoI would assume that the NSA runs enough TOR nodes to correlate traffic from one side of the network to the other side at least a decent percentage of the time. I would also assume that they have a realtime view of the number of bytes entering or leaving any datacenter.
