U.S. preparing for crippling Electromagnetic Pulse attacks targeting the electrical grid

The U.S. Department of Homeland Security is working on a war footing to disrupt potential Electromagnetic Pulse attacks that could disrupt unprotected critical infrastructure within the U.S. and endanger thousands of lives.

DHS said that following the signing of a Presidential order in March 2019 to establish resilience against Electromagnetic Pulse attacks, it has coordinated with the Cybersecurity and Infrastructure Agency (CISA), the Science and Technology Directorate (S&T), and the Federal Emergency Management Agency (FEMA) to address known EMP-related vulnerabilities to critical infrastructure.
