Danish payments company says fears a hundred,000 credit cards hacked

Danish payment processor corporation Nets has advised community banks to block as much as 100,000 credit cards on suspicion their protection may well have already been compromised by hackers, it explained on Wednesday.

Nets, which was floated final month, mentioned the breach was in all probability linked to transactions which has a single online retailer primarily based abroad.

None on the cards had been tampered with however but could possibly be inside the near future, it stated, incorporating that credit card corporations including Visa and Mastercard had opened an investigation.

"By changing quite possibly compromised cards preemptively, banking institutions and outlets can save an amount from the triple digit million (Danish crowns) array, which they could suffer in losses from trades made with stolen credit card details," Nets said.

Danish loan company Jyske Financial institution said on Wednesday it had been blocking and replacing 7,000 cards.
