Critical infrastructure across the country has been put on alert after an attack on two substations in North Carolina, an incident that cut power to tens of thousands for days. Washington law enforcement sources confirm that they received a memo from the FBI warning them about similar attacks to power stations in the Pacific Northwest. The memo read: "Power companies in Oregon and Washington have reported physical attacks on substations, using hand tools, arson, firearms and metal chains possibly in response to an online call for attacks on critical infrastructure. In recent attacks, criminal actors bypassed security by cutting the fence links, lighting nearby fires, shooting equipment from a distance or throwing objects over the fence and onto equipment." Some of those attacks happened within the last couple weeks. One of the largest power providers in the state, Puget Sound Energy, told KING 5 Wednesday that two incidents occurred at their stations in late November. "We are aware of recent threats on power systems across the country and take these very seriously. We are monitoring our infrastructure and can confirm we have had two incidents occur in late November at two different substations. Both incidents are under investigation by the FBI," said a representative of PSE.
