Federal agencies warn foreign hackers are targeting critical infrastructure

The National Security Agency (NSA) and the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) on Thursday warned that foreign hackers are attempting to target U.S. critical infrastructure.

The agencies specifically warned that internet-connected operational technology (OT) assets, used throughout U.S. defense systems, were often the targets of malicious cyber actors attempting to hit critical infrastructure, such as systems providing water, gas and electricity.

As a result, the agencies recommended that critical infrastructure operators and owners take “immediate action” to secure their systems.
