the key of course... what's so hard about that?

of course not... they simply infect machines that are
"sacrificed" for the job and then watch what goes on... there are
plenty of hardware debuggers and custom designed electronics that one could
simply watch and then freeze the operation for a snapshot... it's not an
uncommon thing...

have you ever heard of "TEMPEST" ??  if not, you need to open
your eyes/mind a bit more... it is possible to reproduce everything that
your computer does without any kind of wire linking it to the reproduction
machine... =EVERYTHING= can be seen... even your keystrokes... of course,
it costs hundreds of thousands, if not millions, of $$$ to do but it is
possible, is done on routine basis, and done from a distance...

computers are such radio broadcast stations...
