POWER SUPPLaY

Mordechai Guri of Ben-Gurion University of the Negev in Israel has found a new way to covertly extract data from air-gapped computers.  It's limited (at present) to a bandwidth of about 50 bits per second, and its range is only a few metres, and it can be defeated by background noise, but the concept of a "singing capacitor" is a fairly lovely one  🙂
