The notorious Russian hackers known as Sandworm targeted an electrical substation in Ukraine last year, causing a brief power outage in October 2022.
The findings come from Google’s Mandiant, which described the hack as a “multi-event cyber attack” leveraging a novel technique for impacting industrial control systems (ICS).
“The actor first used OT-level living-off-the-land (LotL) techniques to likely trip the victim’s substation circuit breakers, causing an unplanned power outage that coincided with mass missile strikes on critical infrastructure across Ukraine,” the company said.
