Yeah TZ, 

This one will work but as long as an user's intervention is there but if you
try to simulate key strokes using your code then this is prevented by
current version of ZA.

Dear Florian,

FW> (which might be protected indeed), but to the Internet Explorer windows.
Exactly, the "attack" abuses the fact that windows has no authentication of
the window messages in the queue (in other words it doesn't know WHO send
the message, the APP or the USER in front of the PC). Not knowing who send
the message it happily executes it.

-> WindowsKEY + R
-> TYPE iexplore.exe
-> Press ENTER
-> Send Windowhide
Use your imagination from here on.
