Hilton, Marriott Warn Customers of Epsilon Hack

Computer hackers gained access to the email addresses of customers of several large US banks and other companies in a potentially huge data breach at US online marketing firm Epsilon, reports Yahoo News.

 

The Irving, Texas-based Epsilon, a marketing vendor used by 2,500 companies around the world to send more than 40 billion emails a year, said the hackers obtained email addresses and customer names but no other information.

 

Hilton Worldwide, Marriott, Citigroup and JPMorgan Chase were among those informed by Epsilon that some customer email addresses had been compromised.

 

In a message on its website, Marriott says that it sent e-mail notices to all customers who may be affected by this incident. Sensitive customer information, such as physical addresses, point balances, account logins and passwords, credit card information or other personal data, were not compromised.
