Water Supplier American Water Works Says Systems Hacked

American Water Works — a supplier of drinking water and wastewater services to more than 14 million people — on Monday said hackers had breached its computer networks and systems, prompting it to pause billing to customers.

The Camden, New Jersey-based utility became aware of the unauthorized activity on Thursday, and took protective steps, including shutting down certain systems, American Water Works stated in a regulatory filing. The company does not believe its facilities or operations were impacted by the cybersecurity incident, but is “currently unable to predict the full impact,” it stated.
