Epsilon Press Release

Texas-based company Epsilon released a statement on April 1 saying:

“On March 30th, an incident was detected where a subset of Epsilon clients’ customer data were exposed by an unauthorized entry into Epsilon’s email system. The information that was obtained was limited to email addresses and/or customer names only. A rigorous assessment determined that no other personal identifiable information associated with those names was at risk. A full investigation is currently underway.”

If you are concerned that you could have been one of the victims be extremely cautious of  the emails you open. DO NOT give out any personal information, passwords or social security numbers even though it may look like an email from a reliable source. Epsilon has reassured customers that what was obtained was limited to emails and customer names, but this information can make harmful emails seem legitimate.

Example of Warning Email from Target

Target’s email service provider, Epsilon, recently informed us that their data system was exposed to unauthorized entry. As a result, your email address may have been accessed by an unauthorized party. Epsilon took immediate action to close the vulnerability and notified law enforcement.

While no personally identifiable information, such as names and credit card information, was involved, we felt it was important to let you know that your email may have been compromised. Target would never ask for personal or financial information through email.

Consider these tips to help protect your personal information online:

  • Don’t provide sensitive information through email. Regular email is not a secure method to transmit personal information.
  • Don’t provide sensitive information outside of a secure website.Legitimate companies will not attempt to collect personal information outside a secure website. If you are concerned, contact the organization represented in the email.
  • Don’t open emails from senders you don’t know.

We sincerely regret that this incident occurred. Target takes information protection very seriously and will continue to work to ensure that all appropriate measures are taken to protect personal information. Please contact should you have any additional questions.
