MasterCard International reported yesterday that more than 40 million credit card accounts of all brands might have been exposed to fraud through a computer security breach at a payment processing company, perhaps the largest case of stolen consumer data to date.
MasterCard said its analysts and law enforcement officials had identified a pattern of fraudulent charges that were traced to an intrusion at CardSystems Solutions of Tucson, Ariz., which processes more than $15 billion in payments for small to midsize merchants and financial institutions each year.
Wow. Inside job, nonetheless.
Next time, pay cash!
