Chips? Probably not. Features in coding including the CPU operating system, good chance.
You can cram a lot of code in a little chip.
Planting malware art on the chips themselves is very common and a huge problem for data and operational security.
Chips have become so complex and the circuit densities so high it's very difficult to detect the corrupt circuitry
Producing mission critical chips in places like China is a serious national security risk.
