Air-Gapped Networks Vulnerable to Acoustic Attack via LCD Screens

by

September 10, 2024 at 04:52PM A new method called “Pixhell” can breach air gaps by using sound waves to transmit data via LCD screens. This covert channel attack works by manipulating screen pixels to create sound waves that encode stolen data. High-level security organizations are at risk, though some have built elaborate air gaps to … Read more

New RAMBO Attack Allows Air-Gapped Data Theft via RAM Radio Signals

by

September 9, 2024 at 09:27AM An academic researcher has developed a new attack technique, named RAMBO, that uses radio signals from memory buses to exfiltrate data from air-gapped systems. The technique allows for the capture of encoded files, encryption keys, images, keystrokes, and biometric information at a rate of 1,000 bits per second from up … Read more
