Second, NSA has figured a way to track tor users.
used a hole that WAS already FIXED !!!
Firefox 17.07 had the hole
and that hole WAS FIXED in FF 17.08
and it ran a MICROSOFT .exe file to ping a nsa ran server
you were only vulnerable to it using a OLD UNPATCHED !!!!
version of the tor bundle and if you were using Microsoft WINDOWS
now as to normal tracking
??? yes and no ????
with enough entry and exit nodes under the nsa control it is " ? possible ? " to statistically correlate users times and ip's running through the nodes and start to make good guesses as to who is who
but that will require a LOT of computing power
and that is within a "state ran" body's resources
but will they do it for EVERYTHING ?????
-- not likely
