Hate to be the one to break it to you but YOUR privacy is probably the
least important concern (though I mean no offence by this statement). If
you have this kind of connectivity, I'd be more concerned with what a
potential attacker could do to OTHERS using YOUR compromised host. Also,
you should be picking up on the potential legal ramifications suggested
by this...
