PHILADELPHIA (CBS) — The parent company of ACME Markets has announced a new data breach. Hackers may have gained access to shoppers’ credit and debit card information in 21 states, including Pennsylvania, New Jersey, and Delaware.

If you’ve shopped at ACME from late August to early September, you may want to monitor your credit and debit cards for suspicious activity.

ACME’s parent company, Albertsons LLC, says malicious software was found on networks that processed credit and debit cards in the store.

The company says law enforcement was immediately contacted when the software was detected.

It’s not clear if any customer information was actually stolen.

“It’s more of an inconvenience than anything else,” said Jordan Maria, an Acme shopper in South Philadelphia. “But, sometimes, if it ends up as money being stolen, that’s not a good situation for anybody.”

“We take our responsibility to protect our customers’ payment card data seriously,” said Bob Miller, CEO at AB Acquisition, in a statement about the data breach. “We sincerely regret that our customers’ data was targeted… We are taking appropriate measures to enhance the protection of our customers’ payment card data.”

A statement on Albertson’s website quotes Mark Bates, Senior Vice President and CIO at AB Acquisition LLC. “As soon as we were notified of the incident, we began working closely with SUPERVALU to determine what happened. It’s important to note that there is no evidence at this point that consumer data has been misused,” Bates said. “We understand the inconvenience and concern an incident like this can cause, and we deeply regret that our customers’ data was targeted. “

The company says they will provide complimentary identity protection to affected customers for one year, but as of now it’s not known how many customers, if any, were affected by this possible data breach.
