The CMU team did exploit the relay early bug. But there haven't been
many tor bugs as serious as that.

Sure, browser exploits are common. And yes, Freedom Hosting and
PlayPen users got pwned through Firefox bugs. However, the FBI malware
that deanonymized them exploited a trivial vulnerability in all
default Tor installs: there is no management of Internet traffic that
bypasses the Tor network.

Making Tor browser available without warning about leaks is just plain
irresponsible. About five years ago, Metasploit hosted the NIT used in
the Freedom Hosting attack, as a test for proxy leaks. It was easy to
pass, using firewall rules and/or VM compartmentalization.

One could argue that anyone using Tor for critical stuff should know
that. But obviously, many of them don't. We hear about the ones that
the FBI takes down. But what about the ones who just get killed?

Is it too much to ask for a warning? Maybe a link to Whonix?
