It was reported about a month ago that Whole Foods had experienced a data breach where some customer credit and debit card info was hacked (Whole Foods announces credit and debit card hack). Shortly thereafter it was revealed that some stores in the Greater Philadelphia area were included in the breach.

The cyber attack, which was aimed at Whole Foods’ taprooms and restaurants and not the stores grocery checkout lines, affected the Center City store at 2101 Pennsylvania Ave., as well as stores in Wynnewood, Allentown, Upper St. Clair and Wexford.

Whole Foods said it has taken “appropriate measures” to address the issue, and the investigation is ongoing.
