I think I know what you're referring to.  A few months ago they started putting tamper evident stickers on the top of the 4 screws holding the CPU bracket in place.  By applying light pressure to the center of the screw the torx 10 will puncture the sticker.  It threw me for a loop too when I first saw it too.
