Does anyone know how this happened? It could only be through the Internet because I haven't visited Europe in a decade, I've never lost any of my cards, and I'm the only authorized user on all of my cards. I always order things on the web through secure sites (128 SSL) and I have a firewall. Any recent reports of people hacking into the Citibank site and stealing card numbers? Now I'm getting wary of registering any credit cards on the web for online account access because of this kind of problem. Any thoughts???
