"Securing USB Communication: USBValve to the Rescue"
Originally Published 2 years ago — by Hackaday
USBValve is an open-source tool created by Cesare Pizzi to detect suspicious USB activity. Using a Raspberry Pi Pico and an OLED screen, USBValve pretends to be a storage device and displays information about any unknown USB device plugged into it. This allows users to identify potential malicious behavior, such as unauthorized file access or immediate attempts to write to the filesystem. The low-cost and easy-to-use USBValve provides critical information for addressing real-world USB security threats.
