BURLINGTON, Vt. — Malware code linked to Russian hackers and found on a Vermont electric utility’s computer is further evidence of “predatory” steps taken by that country against the U.S., a Vermont Democratic congressman said Saturday.

The Burlington Electric Department confirmed Friday it had found on one of its laptops the malware code used in Grizzly Steppe, the name Homeland Security has applied to a Russian campaign linked to recent hacks. The company said U.S. utilities were alerted by the Department of Homeland Security on Thursday of the code.

“This attack shows how rampant Russian hacking is. It’s systemic, relentless, predatory,” Rep. Peter Welch said in a statement. “They will hack everywhere, even Vermont, in pursuit of opportunities to disrupt our country.”

Welch said the breach also underscores that sanctions President Barack Obama took against Russia this week were warranted. Russia, which has denied hacking U.S. systems, has been accused of interference in the U.S. presidential election.
