‘GSMem’ malware designed to infiltrate air-gapped computers, steal data

July 27, 2015

Newly designed malware could, if properly replicated, allow an attacker to pick up the data of air-gapped computers, which are typically thought of as relatively secure.

GSMem, as the researchers call it, exploits electromagnetic radiation (EMR) emissions and forces a computer’s memory bus to function similarly to an antenna in order to wirelessly transmit data to a phone over cellular frequencies. The Israeli researchers will open their paper, “GSMem: Data Exfiltration from Air-Gapped Computers over GSM Frequencies” to the public once they present it at the USENIX Security Symposium in August.
