Epsilon breach is quite far reaching

I've worked with Epsilon on a few occasions over the years. Hilton Hotels has outsourced all of the processing associated with their HiltonHonors Loyalty program to Epsilon, which includes having your Credit Card details on file to back up any paid Reservation you make. Hilton has contacted me already.

IDG News Service has confirmed that the following companies have warned customers about the breach (in all some 50 Companies are impacted). 

 - AbeBooks
 - Ameriprise Financial
 - Barclays Bank
 - Best Buy
 - Brookstone
 - Citibank
 - Disney Destinations
 - Hilton Worldwide
 - JP Morgan Chase
 - Kroger
 - Lacoste
 - Marriott International
 - McKinsey Quarterly
 - New York & Company
 - Robert Half
 - Target
 - Tivo
 - US Bank
 - Walgreens

It follows that if you have an American Express Hilton Honors Co-Branded Credit Card, then your details are with Epsilon.

I do hope they've managed to restrict the breach to just e-mail addresses; if they get any deeper then Credit Cards & Date of Birth etc could also be exposed.
