Apple's M1 chip has a vulnerability that can't be fixed without a silicon revision, according to developer Hector Martin. The flaw allows for covert channels that enable two malicious apps to talk to ...
A new attack dubbed 'SmartAttack' uses smartwatches as a covert ultrasonic signal receiver to exfiltrate data from physically isolated (air-gapped) systems. Researchers at the School of Cyber Security ...
Covert Channel Between the CPU and An FPGA By Modulating The Usage of the Power Distribution Network
use Time-to-Digital Converter sensors to observe these power variations. The sensor circuits are programmed into the FPGA fabric using only standard logic components. Our covert channel achieves a ...
“To operate efficiently across a wide range of workloads with varying power requirements, a modern processor applies different current management mechanisms, which briefly throttle instruction ...
Apple's new M1 CPU has a flaw that creates a covert channel that two or more malicious apps—already installed—can use to transmit information to each other, a developer has found. Ars Technica This ...
A new data exfiltration technique has been discovered, which uses a covert ultrasonic channel to leak sensitive information from air-gapped computers to a nearby smartphone device. The adversarial ...
Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
