Wow! Is the trick that we now have powerful microcomputers small enough to fit into a USB plug? That's pretty incredible technology. How many years ago did this become possible? My IT security training is dated, I am aware of the risks of plugging in a random USB key, but just a cable from a helpful "coworker"? Yikes.
> How many years ago did this become possible? I don't know, but I do know that back in 2013 you could get an ARM computer running linux and a webserver with wifi and 16Gb storage in a space the size of an SD card. That is still a bit too big to fit inside a USB plug without being obvious, but not by much. https://hackaday.com/2013/08/12/hacking-transcend-wifi-sd-ca...

Chips have been small for decades. What’s changed over the years is that it’s gotten cheaper and cheaper.
