China's APT31 Suspected in Attacks on Air-Gapped Systems in Eastern Europe

A nation-state actor with links to China is suspected of being behind a series of attacks against industrial organizations in Eastern Europe that took place last year to siphon data stored on air-gapped systems. Cybersecurity company Kaspersky attributed the intrusions with medium to high confidence to a hacking crew called APT31, which is also tracked under the monikers Bronze Vinewood,

COVID-bit: New COVert Channel to Exfiltrate Data from Air-Gapped Computers

An unconventional data exfiltration method leverages a previously undocumented covert channel to leak sensitive information from air-gapped systems. "The information emanates from the air-gapped computer over the air to a distance of 2 m and more and can be picked up by a nearby insider or spy with a mobile phone or laptop," Dr. Mordechai Guri, the head of R&D in the Cyber Security Research

Air-Gapped Devices Can Send Covert Morse Signals via Network Card LEDs

A security researcher who has a long line of work demonstrating novel data exfiltration methods from air-gapped systems has come up with yet another technique that involves sending Morse code signals via LEDs on network interface cards (NICs). The approach, codenamed ETHERLED, comes from Dr. Mordechai Guri, the head of R&D in the Cyber Security Research Center in the Ben Gurion University of the

New Air-Gap Attack Uses MEMS Gyroscope Ultrasonic Covert Channel to Leak Data

A novel data exfiltration technique has been found to leverage a covert ultrasonic channel to leak sensitive information from isolated, air-gapped computers to a nearby smartphone that doesn't even require a microphone to pick up the sound waves. Dubbed GAIROSCOPE, the adversarial model is the latest addition to a long list of acoustic, electromagnetic, optical, and thermal approaches devised by

New Air-Gap Attack Uses SATA Cable as an Antenna to Transfer Radio Signals

A new method devised to leak information and jump over air-gaps takes advantage of Serial Advanced Technology Attachment (SATA) or Serial ATA cables as a communication medium, adding to a long list of electromagnetic, magnetic, electric, optical, and acoustic methods already demonstrated to plunder data. "Although air-gap computers have no wireless connectivity, we show that attackers can use
