Modifying the hardware is virtually imposssible. You need the schematic, 
the pcb layout tools, a vendor who can duplicate the original pcb process, 
and a way to get the modified board into the process stream undetected.

Any hardware change can easily be detected. Take a photo of a known good 
board and a suspect board. Subtract them. Any differences would be 
instantly visible. Do the same with X-Rays. That would capture any changes 
to the internal layers.

It is far easier to do it in software. Modify the firmware so the change is 
invisible. There are virtually an infinite number of ways to do it. 
Untraceable, so no one can tell where it occurred in the process stream.
Selective, so you can turn it on only when a desired target is found.

Someone is running a clickbait article. The whole idea of a hardware attack 
is not worth reading.
