Exploiting SATA Cables: How a Security Flaw Turns Hard Drive Cables into Antennas for Data Leakage

The “SATAn” vulnerability turns SATA cables into antennas to defeat air gap security. Mordechai Guri at Ben-Gurion University seems to be in the death zone of air-physically isolated encrypted computers, or at least giving up their secrets. This hacker exploits a computer’s SATA cable as an antenna to leak data, another example of how many … Read more
