Target was hit with a lawsuit Thursday amid the news that hackers had breached the retailer’s systems and compromised as many as 40 million customers’ credit and debt card data.
The lawsuit in a San Francisco federal court was filed hours after Target acknowledged the hack, which took place between Nov. 27 and Dec. 15. The lawsuit was filed by a California resident, Jennifer Kirk, who wants to make into a class-action suit representing other Target customers also affected by the data breach, Bloomberg Businessweek reports. “Target failed to implement and maintain reasonable security procedures and practices appropriate to the nature and scope of the information compromised in the data breach,” the complaint reads.
Target hasn’t yet commented on the lawsuit.
The hack was one of the largest credit card breaches in U.S. history, and occurred when a computer virus infected its point-of-sale terminals where shoppers swipe their credit or debit cards. The Secret Service is also investigating the breach.
