DEERFIELD, Ill. — Over the weekend, Walgreen Co. announced that a third-party vendor it uses for e-mail promotional messages reported an unauthorized access to its computer systems.
Walgreens said Saturday evening that Epsilon, an Irving, Texas-based provider of multichannel marketing services, reported a breach in its systems and that e-mail addresses were the only information obtained in the incident. The drug store chain noted that no other personally identifiable information is stored with Epsilon.
Law enforcement authorities have been notified and are investigating the matter, according to Walgreens and Epsilon. The drug chain added that it doesn’t send e-mails asking for credit card information, social security number or other personal identity information.
Epsilon reported that on March 30 it detected an incident in which a subset of its clients’ customer data were exposed by an unauthorized entry into Epsilon’s e-mail system. The company said the information that was obtained was limited to e-mail addresses and/or customer names only.
