Data breach revealed by Supervalu

KDWN

EDEN PRAIRIE, Minn. (AP) — There’s been a data breach at a number of Supervalu grocery stores, as well as at some of its stand-alone liquor shops.

The company said Friday that hackers accessed a network that processes store transactions. Account numbers, expiration dates, cardholders’ names and other information may have been stolen.

Stores in Minnesota, Virginia, Illinois, Maryland and Missouri may have been affected.

The cards from which data may have been stolen were used at 180 Supervalu stores, 29 Cub Foods stores and some liquor stores between June 22 and July 17.

Supervalu Inc. says that it hasn’t determined if any such cardholder data was actually stolen and that there’s no evidence of the data being misused, but that it was announcing the data breach out of “an abundance of caution.”
