A new method called SmartAttack exploits smartwatches to covertly extract data from air-gapped systems using ultrasonic waves. This threat reveals the overlooked risk of wearable technology in high-security environments. #SmartAttack #AirGappedSystems
Keypoints
- Smartwatches can be turned into ultrasonic receivers to exfiltrate data covertly.
- The attack involves infection of both the workstation and the smartwatch, enabling data transfer via ultrasonic signals.
- Smartwatches’ constant wear and low suspicion make them effective espionage tools.
- Detection is challenging because traditional security measures can’t monitor sound-based covert channels.
- Mitigation strategies include banning wearable devices and deploying ultrasonic monitoring systems.
