Israel’s Water Authority has reported that a number of cyber attacks on command and control systems of several wastewater treatment plants, pumping stations and sewage water infrastructure were attempted throughout the country. The 24-25 April action appears to have been coordinated but there was no damage to the water supply.
The National Cyber Directorate contacted the heads of the involved companies and institutions instructing them to report any disruptions to operations. Further, companies were advised to change passwords, update control software, and reduce internet connections. There has been particular emphasis on systems involving chlorine control.
YNET News reported: “a source familiar with the incident blamed the attack on the Water Authority's failure to protect sites.” The Water Authority’s response: "The subject of attempted cyber attacks is not new and is constantly addressed by the appropriate experts."
