> Edit: For all the cynics and doomsayers here, consider this: Tor has been around for a long time, but there has never been an uptick in arrests that could be correlated to cracking the core anonymity service. If you look closely at the actual high profile cases where people got busted despite using tor, these people always made other mistakes that led authorities to them.

During WW2, the British cracked the German codes. They would create pretexts for "discovering" where German ships would be, so that the Germans wouldn't suspect that they cracked their codes.

It's impossible for us to know if the US government have cracked Tor, because the world would look identical to us whether they had or hadn't. If the only evidence they have is via Tor, and the individual is a small fry, they will prefer they get away with it rather than let people know that Tor has been cracked.

I just assume the NSA are spending their budgets on something, although maybe it is stuff like side channel attacks.
