Re: [tor-talk] Making TBB undetectable!
Can't TBB devs just patch in a hardcoded 1366x768 window and screen size
Also, if you want true undetectability you need to install a Tor
instance and your OS for TBB in seperate VMs and setup the Tor VM to be
a transparent router for your OS, so even if java/flash/exploit is
executed, it doesn't leak your real IP, since even your OS in the VM is
forced through Tor.
The FBI used an old firefox exploit to execute native code and did plain
IP requests to uncover users. In that configuration they would need an
additional VM escape exploit, which raises the cost exponentially.
