US says cyberattacks against water supplies are rising, and utilities need to do more to stop them

Cyberattacks against water utilities across the country are becoming more frequent and more severe, the Environmental Protection Agency warned Monday as it issued an enforcement alert urging water systems to take immediate actions to protect the nation’s drinking water.

About 70% of utilities inspected by federal officials over the last year violated standards meant to prevent breaches or other intrusions, the agency said. Officials urged even small water systems to improve protections against hacks. Recent cyberattacks by groups affiliated with Russia and Iran have targeted smaller communities.

Some water systems are falling short in basic ways, the alert said, including failure to change default passwords or cut off system access to former employees. Because water utilities often rely on computer software to operate treatment plants and distribution systems, protecting information technology and process controls is crucial, the EPA said. Possible impacts of cyberattacks include interruptions to water treatment and storage; damage to pumps and valves; and alteration of chemical levels to hazardous amounts, the agency said.

McCabe named China, Russia and Iran as the countries that are “actively seeking the capability to disable U.S. critical infrastructure, including water and wastewater.”

  • Why are any of them not air gapped?

    • I've worked on SCADA systems for water automation in a municipal water supply. The meters, valve positions, and sensors can have a tunnel back to the main office and generally aren't accessible unless someone physically breaks into something. With a proper remote solution it's pretty secure (as secure as anything, anyway) to access and manage things from anywhere cutting down water waste and time when problems occur.

      The issue, as usual, is people. I can't tell the story, but I can say that managers and higher ups at municipal water departments will override decisions to make things more accessible without proper protections because they refuse to understand the concept of even the most basic security. Not every water department, obviously, but I can absolutely point to several that will demand easy access with no VPN because they want to use their fucking home computer, and when you won't provide it they'll hire someone else who will.

    • I can pay my bill online. That means there is a connection between the systems. They need to add up all the water everyone in my neighborhood uses compared to how much they pumped into my neighborhood - if there is a difference there is a leak someplace. While each link only needs to be connected to the next, eventually there is a system that is connected to the internet, and so the whole cannot be air gaped. Not to mention the internet is a really easy place to connect everything to.

      Also, it is really nice if you work at the utility to be able to control the pumps and valved scattered all over the city without having to physically go to each one. Or better yet automatic control - which is only possible if all the systems are connected - see above about one of those systems leading to my bill and so must be connected.

      Air gap is useful for a few military systems. Everything else (including most military systems) are better off networked. However we do need to protect the network better.

      • They did all that before the internet. I'm not sure why the internet is necessary now.

        • They did - but it was a lot more work - (and often mistakes were made) and that means costs were higher. Or more likely they didn't do the work as often and so it was a lot longer before they discovered problems.
