Mastercard Security Breach Spreads

Silicon reports that Morgan Stanley customers in the UK are the latest to have been hit by a major security breach that has resulted in thousands of MasterCard credit card details being stolen by fraudsters.

MasterCard notified card issuers of the breach last week and they have been calling affected customers to cancel their cards, close accounts and issue new cards and details.

“Speculation”, writes Silicon, “is now growing that the UK incident could be linked to a massive security breach in the US earlier this month which resulted in hundreds of thousands of card details and PIN numbers being compromised by hackers.”

MasterCard has so far declined to comment on the scale or source of the credit card security breach beyond issuing a statement saying it took immediate action as soon as the breach was discovered.
