The Security Mentor

After payment processor Cardsystems leaked forty million account numbers, Visa and American Express took decisive action. They announced that they won't do business with Cardsystems any more. Mastercard is giving them another chance for some reason. If and when Masterard follows suit, it will be close to a corporate death penalty.

Visa and American Express are right and their action will wake up some of the hundreds of other payment processors. Cardsystems, you see, wasn't even supposed to be storing those account numbers! They said they were keeping them for "research", which is about as credible as the man who says he has a kilogram of cocaine for "personal use".
