Walgreens Reports Data Breach from Personal Mobile Messaging App Error

Walgreens announced on Friday that it inadvertently exposed the personal messages stored on its messaging app due to an internal error. On January 15, officials said they first discovered an error in the Walgreens personal secure messaging features and launched an investigation. They found a data compromise, which allowed personal messages stored on its database to be viewable by other customers. Upon discovery, Walgreens temporarily disabled message viewing to prevent continued exposure and “implemented a technical correction that resolved the issue.” The investigation revealed that some health-related information was breached for a small percentage of its customers for nearly a week between January 9 and January 15, 2020.
