Anfractuosity published a new project:

“Acoustic cryptanalysis is a type of side channel attack that exploits sounds emitted by computers or other devices”

Wavecatcher is a simple PCB that makes use of a MEMS ultrasound microphone, in order to capture audio to around 80kHz, with the goal
of finding interesting ultrasound sources and playing with exfiltrating data from SMPSs etc. via ultrasound.
