Chase, U.S. Bank Customers Warned of E-mail Security Breach


Thousands of customers of JP Morgan Chase and U.S. Bank are being notified today that some of their personal information has been compromised. E-mails have been forwarded to consumers, informing them that someone hacked the computer systems at marketing giant Epsilon. Epsilon markets bank products and services for Chase and U.S. Bank via e-mail. Epsilon, whose customers also include Visa, Citibank and various supermarket chains, acknowledged the incident early today.

"On March 30, an incident was detected where a subset of Epsilon clients' customer data were exposed by an unauthorized entry into Epsilon's e-mail system," Epsilon said. "The information that obtained was limited to e-mail addresses and/or customer names only."

Here's a copy of the letter sent this morning to U.S. Bank Customers:

As a valued U.S. Bank customer, we want to make you aware of a situation that has occurred related to your e-mail address.

We have been informed by Epsilon Interactive, a vendor based in Dallas, Texas, that files containing your e-mail address were accessed by unauthorized entry into their computer system. Epsilon helps us send you e-mails about products and services that may be of interest to you.

We want to assure you that U.S. Bank has never provided Epsilon with financial information about you. For your security, however, we wanted to call this matter to your attention. We ask that you remain alert to any unusual or suspicious emails.

Please remember that U.S. Bank will never request information such as your personal ID, password, social security number, PIN or account number via e-mail. For your safety, never share this or similar information in response to an e-mail request at any time. To learn more about recognizing online fraud issues, visit:
