It doesn’t matter what OS you are running, there are “TEMPEST” style attacks that can be used against it. The original “TEMPEST” spying involved picking up the EM signal from CRTs so you could see what was displayed on the computer’s screen. These days you just tune in to the 2GHz signal emitted by the chipset and it tells you what the computer is processing.

There are other options too, such as installing malware (e.g.: via Autorun or equivalent) which uses hardware onboard the computer to transmit information. That hardware could be the built-in but “disabled” WiFi, bluetooth, or even the sound card.

Even better is if you can use all the mobile phones in the world as mobile bluetooth/wifi/audio listening devices.

It’s not paranoia. They’re not out to get *me*. They’re out to get everyone, as efficiently as possible.
