US retailers Albertson’s and SuperValu have had their payment networks breached by hackers, according to CNN Money.
Both chains announced on Friday that the massive breach impacted their subsidiary stores as well.
“SUPERVALU believes that the payment cards from which such cardholder data may have been stolen were used â€¦ at the 180 SUPERVALU stores and stand-alone liquor stores â€¦ operated under the Cub Foods, Farm Fresh, Hornbacherâ€™s, Shop â€™n Save and Shoppers Food & Pharmacy banners,” SuperValu said.
“The intrusion may also have resulted in the theft of such cardholder data from some cards used during this period at 29 franchised Cub Foods stores and stand-alone liquor stores, which are included in the store list referenced on the SUPERVALU website.”
As the hackers broke into the payment processing network, they may have stolen credit card details such as names, card numbers, expiration dates and the credit card verification code.
In SuperValu’s case the number of affected stores is 228, In Albertson’s case, it rises to 700 affected stores from 1,060 locations.
It is not yet clear which location was first breached, but both retailers share the same payment processing technology.
As the investigation continues, SuperValu announced that the security hole has been fixed.
