I don't know why anyone is doubting this is possible in the first place. From the Snowden leaks we know in 2008 the NSA had an _entire computer_ complete with CPU RAM and an FPGA smaller than the size of a dime [1] that they implanted inside other devices.

The NSA was also actively using COTTONMOUTH II [2] which was a USB header for a motherboard that could be inserted into the supply chain and provided a long range transceiver for software implants to bypass airgapped networks.

Ten years on I would not be surprised that the Chinese have a similar tool in an even smaller form factor. People seem to be treating this like a futuristic sci-fi plot.
