Intelligence Summary
Mandiant helped Cal Water investigate a cyber incident tied to the Iranian hacker group Handala. Handala had claimed it could disrupt the water supply through operational technology (OT) systems. After reviewing activity, the utility found no evidence that OT processes were actually impacted. The findings reduce the likelihood that critical water operations were manipulated remotely. Still, the incident highlights the need for strong OT monitoring and segmentation to prevent future disruption claims from becoming real.
