Researchers from Tel Aviv University and Technion have...found a way to steal data from air-gapped machines while their equipment is in another room.

“By measuring the target's electromagnetic emanations, the attack extracts the secret decryption key within seconds, from a target located in an adjacent room across a wall,” Daniel Genkin, Lev Pachmanov, Itamar Pipman, and Eran Tromer write in a
recently published paper...
“The attack in its current form uses lab equipment that costs about $3000...
“The attacks are completely non-intrusive, we did not modify the targets or open their chassis"The equipment used included an antenna, amplifiers, a software-defined radio, and a laptop. This process was being carried out through a 15cm thick wall, reinforced with metal studs, according to the paper.
