Customer Emails Breached at Big Companies, Banks Kroger, TiVo, Citi, Capitol One are among those affected By John Johnson, Newser Staff Posted Apr 3, 2011 3:14 PM CDT 3 comments Comments Customer emails at lots of big-name companies have been compromised. (Shutterstock) (Newser) – Look out for email scams—ones that appear to come from a legitimate business, not a Nigerian lawyer—in the near future. That's because the nation's biggest email marketer has been hacked, reports Security Week. The breach at Epsilon means that the names and email addresses of customers at its client companies have been exposed. The only bit of good news is that nothing more serious than email addresses appear to have been compromised. The bad news is that Epsilon has a ton of clients, including Kroger, TiVo, US Bank, JPMorgan Chase, Home Shopping Network, Capital One, Citi, the College Board, and Walgreens. "Some may dismiss the type of data harvested as a minor threat," writes Mike Lennon, "but having access to customer lists opens the opportunity for targeted phishing attacks to customers who expect communications from these brands." Citi has already warned its customers about such scams in the wake of the breach.
