American Water Works, the largest US water and wastewater utility, is methodically restoring its IT systems after a major cyberattack. The MyWater billing portal, which had been offline since early October, has been reactivated. The company confirmed that no water or wastewater facilities were affected, and water remains safe to drink. While there is no confirmation yet if ransomware was involved, security experts speculate it could be the cause. The company is working with law enforcement and security teams to investigate the breach and has taken steps to bolster cybersecurity. No late fees will be charged for missed payments during the outage.
