Security researchers from Ben Gurion University in Israel have found a way to retrieve data from air-gapped computers i.e.
computers not connected to internet, using only heat emissions and a computers built-in thermal sensors.
Computers produce varying levels of heat depending on how much processing theyre doing.
As of now the PoC attack allows just eight bits of data to be reliably transferred over an hour.
However this time is enough for cyber criminals to steal passwords and secret keys or give malicious commands.
They will present their findings at a security conference in Tel Aviv next week.
