Mapco Express, the US-based convenience store chain, is notifying customers about a security breach. The company says hackers have managed to gain access to customer credit/debit card information by planting malware on payment processing systems. 

The precise number of affected customers hasn’t been revealed.

However, all individuals that made payments with their debit and credit cards at Mapco locations between March 19-25, April 14-15 and April 20-21 could be impacted.

The affected stores are MAPCO Express, MAPCO Mart, East Coast, Discount Food Mart, Fast Food and Fuel, Delta Express, and Favorite Markets located in Tennessee, northern and central Alabama, Arkansas, northern Georgia, Kentucky, northern Mississippi, and Virginia.

Potentially affected cardholders are being contacted, but all those who suspect that their credit card information might have been compromised are advised to immediately contact their financial institutions.

The FBI and other law enforcement have been notified and an investigation has been launched. The company is working with forensic experts and payment card associations in an effort to determine the precise extent of the damage.

In the meantime, Mapco representatives claim that additional security measures have been implemented to prevent future attacks.
