The companies say that in late August or early September, malicious software was installed on networks that process credit and debit card transactions at some of their stores. Albertsons says the malware may have captured data including account numbers, card expiration dates and the names of cardholders. Supervalu says it believes most of its stores were not affected.

Supervalu supplies information technology services for Albertsons, Acme, Jewel-Osco, Shaw's and Star Market stores. It sold those stores to Cerberus Capital Management in 2013.

The companies disclosed a data breach in August, and they say the two incidents are separate.
