Staples says probing possible payment card data breach

Staples is investigating a possible breach of payment card data and has contacted law enforcement about the matter, making it the latest U.S. retailer to become a possible victim of a cyberattack.

Staples is in the process of investigating a potential issue involving credit card data and has contacted law enforcement," company spokesman Mark Cautela said in a statement late Monday. "We take the protection of customer information very seriously, and are working to resolve the situation. If Staples discovers an issue, it is important to note that customers are not responsible for any fraudulent activity on their credit cards that is reported on a timely basis."
