Circuit found inside a charging cable found “laying around” on my desk.”

I would like help identifying a circuit board found inside one of the ends of a charging cable that mysteriously showed up on the desk in my home office. The board has the following stamped on it:

TX-J2ON
V 1.1 20200622

The charging cable is comprised of a male USB connection on one end and a male micro USB on the other. This end also has an adapter to a male lightning connector. Inside this adapter is where the circuit was found.

If needed, I will provide a picture of the apparatus. I only need to know how to do it. Otherwise, I would like to know if this is something potentially used for malicious purposes.

Thanks
