The USB Neutralizer, built with a Raspberry Pi Pico and a USB splitter cable, addresses many of these threats by immediately wiping the first and last 34 LBA sectors of any connected drive when plugged in. This corrupts the partition structure enough to neutralize most malicious software, allowing the drive to be safely formatted for reuse. The tool is open-source. Limitations include no firmware-level protection, no defense against USB HID spoofing or hardware-level attacks like USB Killers, and no handling of hidden partitions. ## Full article daily.dev links to this article rather than hosting it.
