<speculation> If the attacker can take control of both the guard node of a
hidden service and it's rendezvous point then they can do a traffic
correlation attack to find the IP of the hidden service. If you're running a
hidden service you can mitigate against this by choosing a relay you trust.
Next generation hidden services are being worked on in Prop 224
