Hotel Guest Data Compromised by Epsilon Security Breach

Hackers stole a chunk of customer data from e-mail marketing services company Epsilon last Thursday, in a breach that Epsilon now says affects about 2 percent of the company's clients -- which translates to approximately 50 companies -- many of them in the financial and retail sectors. Several companies in the travel business have been affected, according to, including Hilton HHonors Program, Ritz-Carlton Rewards, Marriott Rewards and Red Roof Inn. An Epsilon spokesperson underscored the point that only names and e-mail addresses were compromised in the breach. Marriott confirmed that the thieves did not have access to sensitive information such as physical addresses, point balances, account logins, passwords or credit card information.
