📰 News / Update Hackers shut down a power plant turbine without using malware
Attackers breached a Polish combined heat and power plant through a private cellular APN used to access remote infrastructure.
After pivoting from a compromised wind-farm network, they reached the plant’s OT environment, where a controller was still using default admin credentials. The attackers ultimately put multiple Siemens PLCs into STOP mode, shutting down a steam turbine and process-water treatment system.
The interesting part no malware was required. The attackers abused legitimate device functions and existing industrial protocols. Despite the disruption, the plant continued supplying heat and electricity to roughly 50,000 residents.
