BadUSB Cables

Born from Mr Self Destruct. The same circuit was used, but I further reduced the size of the board into a more implantable package by getting a real PCB made. You can see this in the Hak5 video I did. While the board is as small as possible using a SOIC-8 package, this could become much smaller if I moved down to a QFN package. However, this wasn't needed even for the USB-C implants. More importantly, I wanted to keep things as cheap, common/easy to source, and easy to work with as I could as a general constraint.

UPDATE: In part 2 of my segments with Hak5, I gave a rundown of the internals of these cables: https://www.youtube.com/watch?v=Kfzk402uTLQ

Initial test, USB-A to micro USB cable:

USB-C cable, via a MacBook charging interface.

Just for fun, implanting in a USB "Condom" as many were proposing this as a solution to the cables.

Lightning USB cable (as seen in the Hak5 video):
