There exist charging only cables, and these look just like normal cables, and are never marked. They come with devices that use usb for charging, and we then put the booby-trapped cables in with our normal ones, assuming they're the same.
I've also seen (a disturbing number of) usb cables where the+5 and ground wires had ~3 ohm resistance - call it a data only cable....
And that's before considering possible damage to the cable.
