Happened to me last year at this time. Someone was using my debit card out in the western US.
At that time I was seldom using it except at ATMs but did buy gas on the edge of town then the local news reported that a number of similar victims had come to light around the same time. Took just over a week for the bank to reimburse my $ 400 something dollars.

These are usually "card skimmers". They install a device on a gas pump
or other reader that skims your card and traps the data.
