Side-channel attack
New Apple CPU side-channel attacks steal data from browsers
A team of security researchers has disclosed new side-channel vulnerabilities in modern Apple processors that could steal sensitive information from web browsers. The Georgia Institute of Technology and Ruhr University Bochum researchers, who presented another attack dubbed ‘iLeakage’ in October 2023, presented their new findings in two separate papers, namely FLOP and SLAP, which show distinct flaws […]
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 […]
