Acoustic Attack
SmartAttack uses smartwatches to steal data from air-gapped systems
A new attack dubbed ‘SmartAttack’ uses smartwatches as a covert ultrasonic signal receiver to exfiltrate data from physically isolated (air-gapped) systems. Air-gapped systems, commonly deployed in mission-critical environments such as government facilities, weapons platforms, and nuclear power plants, are physically isolated from external networks to prevent malware infections and data theft. Despite this isolation, they […]
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 […]
