With the possible theft of millions of consumer email addresses from an advertising company, several large companies have started warning customers to expect fraudulent emails that try to coax account login information from them, The Associated Press reports.
A dozen companies said over the weekend that hackers may have learned their email addresses because of a security breach at a Dallas company called Epsilon that manages email communications.
Among the affected companies are banks like Capital One Financial Corp., Barclays Bank, U.S. Bancorp and Citigroup Inc., JPMorgan Chase & Co., and retailers like Best Buy Co., TiVo Inc., Walgreen Co. and Kroger Co.
The College Board, the nonprofit organization that runs the SATs, also warned that a hacker may have obtained student email addresses.
Walt Disney Co.’s travel subsidiary, Disney Destinations, sent emails warning customers on Sunday.
Epsilon said Friday that its system had been breached, exposing email addresses and customer names but no other personal information.
