The computers that automate water treatment systems across the country were built for durability, not for an internet-connected world. Many still accomplish their fundamental function, but as cyberattacks on the sector mounted this summer, water industry officials say those aging systems, especially internet-exposed operational technology and programmable logic controllers, remain among the easiest ways for adversaries to break in.
Tom Dobbins, executive director of the Water Information Sharing and Analysis Center or WaterISAC, told CyberScoop the sector’s biggest ongoing weaknesses include exposed OT, vulnerable PLCs, insecure connections through integrators and poor cyber hygiene at smaller utilities, which have pushed the center to make threat sharing faster across the sector.
“We have been under attack, and our enemies, the threat actors, are stepping up their activity as the U.S. is involved in a number of conflicts around the world,” Dobbins said.
That includes not only threats from Iran, the nation the U.S. government reportedly believes is behind this summer’s water facility attacks, but also China and Russia, he said.
WaterISAC is announcing a partnership with Cyware Wednesday to use its threat intelligence platform, selecting the company in part because of its existing relationships with other industry ISACs, Dobbins said. The ISAC already has a partnership with the National Rural Water Association to serve 20,000 of the water sector’s smallest utilities, and Dobbins said Cyware would help its analysts further.
