Watch out! Hackers may have your info.

The Associated Press reports the possible theft of millions of e-mail addresses from a Dallas-based company.

A dozen companies said over the weekend that hackers may have learned their email addresses because of a security breach at a Dallas-based company called Epsilon that manages email communications.

Among the affected companies are banks such as Capital One Financial Corp., Barclays Bank, U.S. Bancorp and Citigroup Inc., JPMorgan Chase & Co., and retailers including Best Buy Co., TiVo Inc., Walgreen Co. and Kroger Co.
