Newsflash: Epsilon email data breach – millions of email addresses stolen

Email service provider Epsilon has been hit by a hacking attempt which affected many top level companies including Citi, Disney Destinations, Best Buy and Target. The press release posted on Epsilon’s website last Friday states that just 2 percent of total clients was hit, and only email addresses and/or customer names were obtained. As Epsilon has more than 2500 clients and sends out more than 40 billion emails a year, even 2 percent amounts to 50 companies being hit.

The full list of companies hit so far:

AIR MILES Reward Program (Canada)
Barclays Bank of Delaware ( Barclay’s L.L. Bean Visa card)

Oddly enough Benefit Cosmetics is a former client, according to they raise the question as to why the Benefit Cosmetics data was still on the Epsilon servers at the time of the data breach.
