This is why I've been verifying Tor downloads using
out of band fingerprints of signing key.

Just because active attacks are more expensive than passive attacks
and are fundamentally detectable, don't assume they're not being
used in highly targeted cases.

If you have ever been under telco surveillance, that's enough
effort already spent to warrant slipping you some custom malware with
no added bill of materials.
