A significant cyberattack on American Water, the largest regulated water and wastewater utility in the U.S., has raised concerns about the protection of critical infrastructure. The New Jersey-based company, which serves over 14 million customers, paused billing activities during its investigation into the attack, even as water services remained uninterrupted. Experts noted that the cyberattack appeared to focus more on IT systems rather than operational disruptions, underscoring a growing recognition of vulnerabilities within essential infrastructure. The Cybersecurity and Infrastructure Security Agency has called for immediate measures to enhance security for water systems, highlighting that many utilities fail to meet compliance standards intended to prevent breaches.
