Last year, private researchers CT scanned many apple's Thunderbolt 4 connectors and were astonished to find a 10-layer PCB with lots of active electronics.
A lot of people saw the scan and wondered whether malicious electronics could be hidden in a tiny USB connector
and the answer is YES.
It can even look like an ordinary USB cable (video on the right), but it can log keystrokes, inject malicious code, and communicate with an attacker via WiFi, etc.
You can explore the scans for yourself!
Uh.... yeah. You can buy them here. The NSA has had these for who knows how long.
There are also detectors.

This is a very well known thing? Coinkite sells a cable that’s “power only” and even encourages using their 9V adapter if you want to eliminate that entire class of attack.
Sure you can mitigate one vulnerability at a time, the point is more that HWWs open more cans of worms than they close... It's just another hustle
This is really cool. I have one of those really expensive Apple cables for charging/connecting my laptop my monitor which I bought after a cheaper usb-C cable failed on me. I always suspected I might've gotten robbed but it looks at least somewhat worth it.
They have a video exploring and explaining the scans:
view on youtu.beThat cable is pretty wild. Honestly looking at these cables makes me think we've lost the plot with computers.
I'm not trying to undercut the engineering. Just saying...
I think it's a sign of
I'm not sure how we don't end up with smart cables.
USB is dangerous!
I want a CT scanner.... that's my take away
So that's why they're so expensive!
I forget how many boomers here didn’t come at Bitcoin from the tech or FOSS side and come at it from a purely economic one.
