A new attack dubbed 'SmartAttack' uses smartwatches as a covert ultrasonic signal receiver to exfiltrate data from physically isolated (air-gapped) systems.

Most wireless systems involve time-varying multipath channels, where the negative effect of the phase noise cannot be ignored. The phase noise can be introduced by imperfect phase-locked loop ...

Patrick Yang, CTO at WCH, has recently unveiled the CH570 RISC-V SoC with 2.4GHz wireless and USB 2.0 (host & device) as an upgrade to the popular ...
