On April 23, the Israeli government issued an alert in response to an attempted cyber attack on the nation’s water infrastructure. According to an alert published by Israel’s National Cyber Directorate, the attack targeted industrial control systems at wastewater treatment plants, pumping stations and sewage facilities.

According to Israeli news outlet Ynet, the attack on the nation’s water authority occurred Friday and Saturday and was halted before damage could occur.

“We have received a number of reports regarding a cyber attack on the… systems,” said Daniel Lacker, head of the water authority’s security department, according to Ynet. “No damage was reported during the incident.”

In light of the recent attack on supervisory control and data acquisition systems in the water sector, the Israeili government  has advised organizations in the energy and water sectors to immediately change control system passwords, reduce internet connectivity, and ensure that the most up-to-date software is installed.

Cyber attacks on water infrastructure, and in the utility industry as a whole, are a major concern. According to a survey of more than 20,000 utility employees, published by Bridge Energy Group in 2018, cyber threats are feared to have the biggest impact on operations.
