From Brian Krebs:
Here’s the kicker: A comparison of the ZIP code data between the unique ZIPs represented on Rescator’s site, and those of the Home Depot stores shows a staggering 99.4 percent overlap.
Brian Krebs is incredibly smart and also fairly reserved with his FUD. I believe him and it probably means another massive release of credit card data. This is only going to get worse until companies suffer such staggering loses that security becomes as important as developing a new logo. Good security and track records should be a major selling point.
