Many thanks to Sara Martínez for a great conversation about security testing and for the USB Condom gift, which I didn't realise was a thing.

USB Condoms can also be known as a USB data blocker or USB privacy device. They sit between your device and a USB port to prevent data exchange while still allowing for power transfer.
