American Water warns of billing outages after finding hackers in its systems

American Water disclosed unauthorized activity in its internal networks discovered on October 3, leading the company to disconnect or deactivate affected systems and pause customer billing while investigators and law enforcement respond; the company reports no current impact to water and wastewater operations. The report highlights broader U.S. government warnings about state-backed groups (for example, "Volt Typhoon") targeting U.S. water infrastructure, but does not confirm attribution for this intrusion.
