Not really a new threat, although I'm curious if they really mean the microprocessor, or just the main system unit. Picking up keystroke data from the microprocessor itself is an impressive trick. I'd have expected the density of the circuitry to be more of a problem. FYI, for those who want to Google more, the common name assigned to this kind of thing is "TEMPEST", from an old NSA project that investigated the phenomenon decades ago. The more technical and generic term is "EMSEC" (Emissions Security), but the TEMPEST name has stuck (prolly because it sounds way cooler). Much of it is still classified. -- Ben
