Welcome to the weekend everyone! What better way to kick things off than with the news that one of the nation’s largest supermarket operators has had its card payment system compromised at chains like Albertsons, Jewel-Osco, Shaw’s, and ACME.

According to AB Acquisition LLC, which operates these chains and others, the company “recently learned of an unlawful intrusion to obtain credit and debit card payment information in some of its stores.”
