Summary: A survey of roughly 600 water and wastewater utility employees by the Water Sector Coordinating Council found that 37.9 percent of utilities had identified all IT-networked assets, while just 30.5 percent had identified all operational technology assets. The report follows incidents including a 2019 hack of a Kansas public water system by a former employee, the February 2021 Oldsmar, Florida breach that raised sodium hydroxide to 100 times normal levels via a TeamViewer account, and a January attempt on a San Francisco Bay Area plant using a former employee's TeamViewer credentials.
