There have been recent rumors about another data breach of a credit card processor (coverage: SCMag, Dark Reading). Allegedly on the scale of Heartland and that is bothersome. So we are forced to call is Breach X for the time being. There is a high likelihood that your credit card data has been compromised as a result of either Heartland or Breach X. If you are lucky, then your bank will just issue another card and you ll need to go change all your numbers and update all your e-commerce sites.
