So Minnesota-based Supervalu, an operator of grocery stores, had a data breach in the midwest last week. If you’ve shopped at Cub Foods, Farm Fresh, Hornbacher’s, Shop ’n Save, Shoppers Food and Pharmacy, or former Supervalu chains Albertsons and Jewel-Osco between the dates of June 22 and July 17, and you paid with a credit or debit card, call your credit card company or bank.
If you need a new card, it’s much faster to let them know than for them to try to figure it out. And in the meantime, continue to use the card for everyday purchases to establish normal behavior. Don’t run up debt, but you want to establish where you are, so if someone buys the card info and tries to use it, it will stick out. And if their small transaction did happen to go through and they tried a larger one, it’s a little less likely to go through if you’ve run the balance up a little. These are little things you can do to make things harder for the criminals and easier for the banks, and potentially make it easier for the authorities to find the criminals.
