New York City -- Walgreens said a marketing and communications vendor that it uses, Epsilon, has informed the company about unauthorized access to its customers' email addresses, the Associated Press reported. The retailer joins JPMorgan Chase & Co. and grocery operator Kroger Co., which also use the same vendor to send emails, as the latest company to announce a breach of information.
In a statement, Walgreens said law enforcement authorities have been notified and are investigating the matter.
Epsilon issued a brief statement on Friday saying it was undergoing a full investigation after the breach was discovered for a subset of customer client data.
Walgreens said email addresses were the only information obtained in this incident and no other personally identifiable information is stored with Epsilon, according to the report.
Kroger said a database with customer names and email addresses was breached, but not any information connected with their 1-2-3 Rewards Mastercard accounts.
