Iran-linked hackers disrupt systems tied to US critical infrastructure, officials say

U.S. agencies say Iran-linked hackers have disrupted systems tied to water, energy and other critical infrastructure and issued an urgent notice to private-sector operators.

Iran-linked hackers are reported to be disrupting systems connected to key U.S. infrastructure, federal officials said. The Cybersecurity and Infrastructure Security Agency issued an urgent notice to the private sector describing attempts to affect water, energy, transportation and communications systems. Multiple federal agencies echoed the advisory as tensions between the U.S. and Iran were publicly heightened. Officials said some disruptions have already occurred, without providing detailed descriptions of affected sites. What officials reported: - The CISA notice said the attackers are backed by Iran's Islamic Revolutionary Guard Corps and have targeted devices across multiple critical infrastructure sectors, including government services, water and wastewater systems, and energy. - Agencies reported the activity has led to disruptions across several U.S. critical infrastructure sectors, though they did not specify all affected systems. - The article mentions the attackers targeted programmable logic controllers and products made by Rockwell Automation's Allen‑Bradley, which are commonly used in industrial control systems. - The CISA advisory was echoed by the FBI, NSA, the Environmental Protection Agency, the Department of Energy, and U.S. Cyber Command. Summary: Officials say the reported intrusions have prompted coordinated warnings from multiple federal agencies and concern about potential impacts on vital systems. The advisory urged utilities and government agencies to check that programmable logic controllers are not connected to the Internet as a precautionary measure. Undetermined at this time.
