Escalating threats to infrastructure confirm our need to harden the electric grid

It’s official: The U.S. Department of Homeland Security and the FBI confirmed this month that our nation’s nuclear, energy, water, aviation, and critical manufacturing sectors as well as some government entities have been the targets of repeated cyberattacks dating back to at least May 2017.

In a “joint technical alert” circulated by email, the agencies said that attacks had compromised some of the targeted networks, but they did not describe the extent of the infiltration or damage or identify any specific victims.
