Minneapolis-based Target is briefing state attorneys general about the theft of 40 million credit and debit card numbers of customers.
Target invited the attorneys general to an afternoon conference call Monday with the retailer's top lawyer. The company said it wanted to bring the law enforcement officials up to date on the data breach.
Target said it is working with the U.S. Secret Service and the Department of Justice on an investigation into malicious software that affected Target's check-out system in U.S. stores. The Secret Service has asked that details of the investigation not be shared, the company said.
The Secret Service and U.S. Attorney's Office for Minnesota had no comment.
Also on Monday, Chase, the U.S. consumer and commercial banking business of JPMorgan Chase & Co., raised cash withdrawal and spending caps it placed on debit cards at risk from the Target breach, while saying it plans to replace the cards. Chase has not put restrictions on credit cards.
Unless customers see fraudulent activity on their accounts, there is no urgent need to call about their credit or debit cards, Target said.
