CSO – JPMorgan Chase & Co. has said they plan to issue breach notifications to nearly 500,000 customers, or two percent of the bank’s 25 million UCard users, after hackers breached their network in July. However, because there’s no evidence that funds were stolen, the bank will not issue replacement cards.
On Wednesday, several state agencies were notified of a data breach that took place in July, after hackers compromised UCard servers maintained by JP Morgan Chase & Co. The incident resulted in the potential loss of hundreds of thousands of records.
The breach itself was detected and fixed in September, but the specifics of the attack remain undisclosed. While normally encrypted, the bank said that the records compromised during the attack appeared in clear text temporarily while the breach taking place. Moreover, the bank stressed that the breach in July only affected the prepaid UCards, and none of the other cards brands that they support.
