Hackers are targeting US water systems. Here’s what that means.
Government officials are warning about a wave of cyberattacks on water utilities in the US. Here's how hackers can impact water systems.
At least seven US states have reported cyberattacks on water systems to the FBI since July 27, according to the agency. Hackers have remotely accessed devices and altered water operations, potentially limiting utilities' ability to monitor and control their systems. Cybersecurity experts express concern over vulnerabilities in water and other critical infrastructure, including energy and healthcare.
In April, the FBI and other federal agencies warned about ongoing Iran-affiliated cyber threats targeting water systems. The hackers accessed internet-connected devices called Programmable Logic Controllers, which can be programmed to maintain water pressure or alert workers of issues, said Joshua Corman, an expert on public safety and resilience.
Disruptions to water service can affect businesses, hospitals, and fire response, with no water posing dire consequences for healthcare facilities. Experts call for stronger cybersecurity measures for water utilities, while agreeing universal standards are challenging due to the variety of systems in use.
