Norway’s largest bank, DNB, was hit by a fraud attack. 26 000 of the bank's cardholders were targeted in an attempt to draw money out of their accounts.
Andreas Nyheim communications advisor in DNB confirmed the situation: ”We can confirm that a card series of a total of 26 000 cards have been under fraud attempt.”
The fraud attempt
The fraudsters sought to carry out small transactions, of only a few Norwegian Kroner per transaction, from each cardholder. It was set up as a numbers game, stealing a small amount from many people whilst disguising it as an additional transaction fee. By going after smaller amount they were more likely to go unnoticed.
DNB acted quickly and informed customers whose cards were targeted. The same day as discovering the fraud attempt DNB, as a safeguard, closed the targeted cards for any e-commerce use.
”No customers have suffered financial losses. In the few cases where the transaction has gone through, these have been reversed, so that the sum is returned to the affected customers”, Nyheim said.
He went on to explain that DNB now is in full control over the situation. “We have obtained an overview of the situation and implemented necessary security measures”, he emphasised.
Customers not at fault
DNB made it clear that they are fully aware that the security breach did not originate from the affected customers themselves.
Nyheim explained how the method of hacking is known to the bank: "It is about short-number testing, where you try within the series and guessing on many different cards. Customers are innocent."
We believe that information should be free and will therefore never put up a paywall.
