The data breach at Epsilon Interactive, an e-mail marketing firm, means you could receive e-mails from legitimate companies asking for your information. Tony Green, in the Oregon Attorney General's Office, says they expect phishing e-mails to be sent. Some of the companies that use Epsilon are Walgreens, American Express and U.S. Bank.  Don't click links on the e-mail; it could download a virus on your computer. If in doubt, call the company that sent the e-mail.
