It may be the largest breach of customer information stored on computers in U.S. history.
One or more hackers has stolen personal e-mails and names of customers of large companies including Citigroup, JPMorgan Chase and Capital One credit cards. Other companies hit in the massive hack are Walgreens, TiVo, the HSN teleshopping service and Kroger grocery stores. What’s more, the size and scope of the data heist isn’t completely known yet at the online marketer Epsilon. Epsilon says a hacker broke into its computers and raided the customer files of clients. Epsilon is a division of Alliance Data Systems and sends some 40-billion e-mail ads annually. Both Citigroup and Capital One say no account information has been compromised. Other Epsilon customers include Verizon, Hilton Hotels, Kraft Foods and drugmaker Astra Zeneca. Law enforcement is reportedly investigating.
