HP laptop leaks/transmits its built-in mic audio somewhere around 24Mhz

... and just found out my laptops are bugged.

Joking aside, this is a little scary. The NSA actually publishes documents for securing workstation hardware [1], where they suggest physically removing webcam, bluetooth, and mic hardware. How many webcams and mics are around you, right now? I have 3 cameras and 2 mics (phone and laptop). Are they off?
