I got a charge made on my bank account from an email that I don’t know and for security reasons they only give me the first and last character and the amount of characters. They will only help me if I can authenticate by giving them the email address.

Is there a way to find it only knowing those things?

I found a debug port on a device of mine and I was wondering if anyone new anything about it as I can’t find anything myself. I’ll post a picture if needed but it’d a 6 pin in line and the 1st and 5th pad are bigger then the rest. I’m not new to using jtag and stuff but I haven’t seen this port before so I’m looking for assistance identifying it and getting a pinout before I mess it up.
