That's strange. I also had 2 different Chase credit cards with fraudulent charges over the past couple of weeks. (In both cases, the card was being used for online orders w/ Uber, etc. and I had the physical cards with me, so it seems like they just stole the card numbers.) I thought it was strange but assumed maybe someone had been able to obtain the card numbers while I was traveling. Now I'm thinking there may be a much larger hacking situation going on with Chase account numbers.
