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

Locked

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

My guess would be that it is some type of voltage regulator but it’s hard to say for certain.

What is the cable used to charge? Phone, computer, UPS battery backup, etc.???

The cable is for charging an iPhone I suppose. I don’t know how to download a picture of it. Is it possible to do so?

Even if you could post a picture, it would be next to impossible to determine what the microchip does by looking at it. You might try reaching out to Apple directly if they were the one who manufactured the cable and if not, whoever manufactured it. Is it a security question or concern ?

It is, in fact, a security concern. Within the last week, one of my accounts has been hit twice. The first I can see. There’s a lot of mischieve going on out there. The second time was somewhat more difficult to swallow. The bank had canceled the card and issued another. I had not yet received the new card when it was hit for another set of purchases. I feel somehow the new card’s information was extracted from my iPhone. My research uncovered the O.MG which is a cable used for keylogger attacks on iPhones.

Your 2 issues could be unrelated to the cable. Does anyone else have access to your computer? Is this the cable that came with your computer or did you recently swap cables? Where and how did you find this circuit?
