See also my analysis from last year [1]. Sniffing ~25 selected C-class
networks with Tor relays gives your ~25% end-to-end correlation
capability. Surely NSA would be able to install 25 designated probes
in 6 years. My guess is that they have the capability, but reserve it
for high-profile national security targets (see last slide).
