Second cyberattack hits SuperValu grocery stores' payment systems

The Minnesota-based supermarket chain says technology installed after the first attack greatly reduced the severity of the second

SuperValu, the grocery store operator hit by a cyberattack in June and July, has suffered a second attack on its payment processing system, it said Monday.

The Minnesota-based company said the more recent attack involved different malware installed on the part of its computer network that processes card payments at some of its Shop 'n Save, Shoppers Food & Pharmacy and Cub Foods stores. But the company said it believes that cardholder information is largely safe.

While the second breach is no doubt embarrassing for the company, the severity of the attack was partially mitigated by technology it had deployed since the first breach, it said.

While the malware was installed at numerous stores, it only succeeded in capturing payment card data between Aug. 27 and Sept. 21 from some checkout lanes at four Cub Foods franchise locations in Hastings, Shakopee, Roseville and White Bear Lake, Minnesota.

The data included account numbers, and in some cases the expiration date, the cardholder's name and other data, but even if it was collected, SuperValu said it doesn't believe the captured data was transmitted to a third party.

SuperValu said it has launched a second investigation and that it believes it has eradicated the malware.

The first attack hit the company's payment processing network between June and July and could have resulted in the theft of account numbers, cardholder names, expiration dates and other data from payment cards at some stores in the Shop 'n Save, Shoppers Food & Pharmacy, Farm Fresh and Cub Foods chains.

On Monday, SuperValu said investigations into the first breach are continuing and it hasn't been able to find evidence that any cardholder data was stolen.

The breach is the latest in a growing number to hit payment systems at retail stores.

It really doesn’t get more “gaming laptop” than this.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
