Hackers Breach Polish Power Plant Controls via Private Cellular Network and Shut Turbine
Attackers shut down a steam turbine and the process-water treatment system at a Polish combined heat and power plant by coming in over the private cellular network the local grid operator uses to reach remote equipment.
The plant supplies heat to roughly 50,000 residents. Recovery began at about 7:30 a.m. while the intruders were still active inside the network, and customers lost neither heat
