Be wary of unusual emails: The names and email addresses of customers of Citigroup, College Board, Walgreens, HSN, and several other large companies were exposed after a hacker broke into online marketer Epsilon’s databases. Epsiolon insists, however, that credit-card numbers and Social Security numbers are safe. The breach is believed to be one of the largest in U.S. history.
