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
To be honest, the article wasn't very clear on this, but do we know that the "secondary die hidden under the primary microcontroller" was for malicious purposes?
I would expect a pen-testing cable to be for more sophisticated than a regular USB-C cable.
It seems like tomshardware is hinting at the possibility of supply chain attacks, without referencing any newly identified examples.
I'm not sure I understand what you're trying to ask.
The cable exists for malicious purposes. That's the purpose of the cable.
The article seems to be just comparing it to standard cables which just have the circuitry for charging. Since this cable has additional capabilities, can host its own wifi network, etc. it needs additional controllers and antennae to support that.
Actually reading more of the article... It seems like the author doesn't really know what the OMG cable is and is trying to frame it as some sort of unexpected thing. Comparing it to a standard USB cable makes no sense.
