The most secure computers in the world can't “Google” a thing—they are disconnected from the Internet and all other networks. The U.S. military and the National Security Agency rely on this attack-prevention measure, known as air-gapping, as does The Intercept, the media outlet co-founded by Glenn Greenwald, who was instrumental in disclosing the nsa's extensive domestic surveillance program. But where there's a will, there's a way: a team of doctoral students at Ben-Gurion University of the Negev in Israel announced it can obtain information from an air-gapped computer by reading messages encoded in the heat given off, like smoke signals, by its processors.
