Columbus Water Works: Columbus Water Works hit by cybersecurity attack, no threat to public water supply

Cyberattack Disrupts Columbus Water Works Operations, Manual Systems Deployed

On Monday, July 27, Columbus Water Works (CWW) in Columbus, Georgia, fell victim to a cybersecurity attack that disrupted automated data transmission systems, including water usage monitoring. Emergency Management Agency Director Chance Corbett confirmed the incident, stating that CWW immediately transitioned to manual operations to maintain service continuity.

While the attack impacted certain operating systems, Corbett emphasized that water service, supply, and quality remained unaffected for Columbus residents. No public notifications were issued, as the incident posed no immediate threat to safety or infrastructure. The Georgia Emergency Management Agency (GEMA) and the FBI were notified, and an investigation is underway to identify the source of the breach.

CWW is actively securing vulnerable systems, though some operations remain offline as staff conduct manual checks. Full restoration is expected by the end of the week. Corbett declined to speculate on potential links to recent cyberattacks on water systems in Minnesota, which have been attributed to Iranian threat actors. The origin of the Columbus attack remains undetermined.
