American Water rinsed in cyberattack, turns off app

American Water, which serves over 14 million people, detected unusual network activity and confirmed a cybersecurity breach that prompted the company to isolate affected systems, suspend its MyWater billing app, and engage law enforcement and external investigators. The company reports no impact to water operations or water quality, resumed customer portal access after remediation, and framed the incident within a wider pattern of nation-state and ransomware threats against the U.S. water sector.
