USB-C cable CT scan reveals sinister active electronics — O.MG pen testing cable contains a hidden antenna and another die embedded in the microcontroller

A small package with a huge malicious potential.

Industrial CT scanner manufacturer Lumafield imaged an O.MG pen testing USB-C cable, revealing sophisticated electronic components secreted within the connector. Lumafield said that it did this scan after it published the internal view of Apple’s Thunderbolt 4 (USB-C) Pro Cable, which revealed a lot of sophisticated electronics inside. With electronics that look as simple as a charging cable getting more and more complicated every year, anyone, from run-of-the-mill hackers to state-sponsored attackers, could get into the manufacturing process of a device and insert systems that will compromise the final product, or worse.
