New RAMBO Attack Uses RAM Radio Signals to Steal Data from Air-Gapped Networks

A novel side-channel attack has been found to leverage radio signals emanated by a device's random access memory RAM as a data exfiltration mechanism, posing a threat to air-gapped networks. The technique has been codenamed RAMBO short for "Radiation of Air-gapped Memory Bus for Offense" by Dr...

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...

Exfiltrating Data from Air-Gapped Computers Using Screen Brightness

It may sound creepy and unreal, but hackers can also exfiltrate sensitive data from your computer by simply changing the brightness of the screen, new cybersecurity research shared with The Hacker News revealed. In recent years, several cybersecurity researchers demonstrated innovative ways to...
