Credit card compromised?

I made a purchase on eBay. I've done so on occasion over the years with no issues. Within a few days, I got an alert from my bank about suspicious activity and had to cancel my credit card due to 6 or 7 fraudulent charge attempts.

That card is set up to pay several bills and I use it weekly at the same grocery store and restaurants near me.

The item sent to me was not anything like the photos and description of the product. That's a first for me when ordering from eBay and seemed odd.

Has anyone ever suspected their CC was compromised after an eBay purchase?

I realize this could just be a coincidence. Just curious.
