Side-channel attack
New PIXHELL acoustic attack leaks secrets from LCD screen noise
A novel acoustic attack named ‘PIXHELL’ can leak secrets from air-gapped and audio-gapped systems, and without requiring speakers, through the LCD monitors they connect to. In a PIXHELL attack, malware modulates the pixel patterns on LCD screens to induce noise in the frequency range of 0-22 kHz, carrying encoded signals within those acoustic waves that can […]
New RAMBO attack steals data using RAM in air-gapped computers
A novel side-channel attack dubbed “RAMBO” (Radiation of Air-gapped Memory Bus for Offense) generates electromagnetic radiation from a device’s RAM to send data from air-gapped computers. Air-gapped systems, typically used in mission-critical environments with exceptionally high-security requirements, such as governments, weapon systems, and nuclear power stations, are isolated from the public internet and other networks to […]
Linux kernel impacted by new SLUBStick cross-cache attack
A novel Linux Kernel cross-cache attack named SLUBStick has a 99% success in converting a limited heap vulnerability into an arbitrary memory read-and-write capability, letting the researchers elevate privileges or escape containers. The discovery comes from a team of researchers from the Graz University of Technology who demonstrated the attack on Linux kernel versions 5.9 and 6.2 (latest) using […]
