Hackers with ties to the Russian government have reportedly made their way into software that runs a good chunk of the nation’s critical infrastructure.

ABC News reports that the feds say this could cause an economic catastrophe.

The Department of Homeland Security says the bug has been in play since at least 2011, but officials allegedly have no idea when hackers might activate it.

Analysts say just about every critical system is at risk – energy, water, banking, transportation and more.

Some national security sources say that that the Russian government may have backed the entire thing.

Mark Rasch, a former federal computer crimes prosecutor, was on “Shepard Smith Reporting” to discuss.

“This is where the war is gonna be fought next. It’s not just gonna be fought on the battlefield, it’s gonna be fought on the Internet as well,” Rasch said.
