To Paul and William,
Did either of you think to crack open your laptop cases and check for embedded key logging hardware on the MB.. it could be in there... that tiny mislabeled capacitor near the USB bus would be a good hiding place... or have you been blindly typing away on those keyboards for several years...? Does the firmware for your wireless card ever overstep its bounds and poke around a bit... perhaps to collect info from the key logger? That same wireless firmware could probably have access to your network without your knowledge... Isn't it the government that stipulates that the firmware be distributed in binary form only...? And be sure to "mute" the mic on your machine... they'd never be smart enough to use the speakers in reverse to accomplish the same thing :)
All kidding aside; do either of you audit the source code of your OS personally... or blindly trust all RH employees "have your back"?
When it comes to "security", don't we all just, eventually, bury our heads in whichever sand makes us feel safe?
