In my TechRepublic column Air-gapped computers are no longer secure, researchers at Georgia Institute of Technology explain how simple it is to capture keystrokes from a computer just using spurious electromagnetic side-channel emissions emanating from the computer under attack. Daniel Genkin, Lev Pachmanov, Itamar Pipman, and Eran Tromer, researchers at Tel Aviv University, agree the process is…
