American Water Works IT Systems Hit By Cyberattack; OT Unaffected

American Water Works reported unauthorized activity in its IT networks on Oct 3, activated incident response and law enforcement, and disconnected or deactivated certain systems (including the MyWater billing portal), resulting in paused billing and limited call center services; the company says water and wastewater operations were not impacted and is investigating whether customer data was compromised. Analysts suspect a ransomware-style attack amid broader increasing threats to water utilities, but there is no confirmed data exfiltration or OT impact at this time.
