(Ryan Keene)When someone wrote me to say there was a data breach at the company behind several major supermarket chains — including Albertsons, Jewel-Osco, ACME, Star Markets, and Shaw’s — I thought, “That happened about six weeks ago, didn’t it?” Alas, the company has announced it is the victim of a new, separate attack. AB Acquisition LLC is the name of the company, which probably doesn’t mean anything to you, but its various supermarket brands are well known around the country. It announced late on Monday afternoon that its IT services provider SUPERVALU had notified it of a more recent “attempted criminal intrusion” from hackers trying to obtain credit/debit card information from these stores. According to AB Acquisition, this is a different strain of malware than the one that compromised the stores’ payment systems from late June through mid-July of this year.
