Hackers have broken into the credit and debit card payment networks at two of the nation's most popular supermarket store chains: Albertson's and SuperValu.
The chains announced the data breach Friday morning. The massive hack impacts their umbrella of stores, as well.
That includes Albertson's Acme, Jewel-Osco, Shaw's and Star Market supermarkets, as well as SuperValu's Cub Foods, Hornbacher's, Farm Fresh, Shop 'N Save and Shoppers Food & Pharmacy.
The extent of the damage isn't yet clear, and the grocery chains haven't yet said how many customers might be affected. SuperValu said it knows hackers broke into the computer network that processes card payments, but it's unsure whether they managed to take the data.
If they did, hackers made off with the typical information stored on a credit card's magnetic stripe: your name, card number, expiration date and the three-digit security code.
