“Four Methods Hackers Use to Steal Data from Air-Gapped Computers”

Security researchers have demonstrated ways in which data could be extracted from air-gapped computer systems through the development of covert channels. These channels are characterized into 4 different types, which include electromagnetic, acoustic, thermal, and optical. This article further discusses how hackers could abuse these channels to steal data, the insecurity of light-emitting diodes (LEDs), and other related research.
