Hackers breached a small Polish energy plant via private APN last year

Hackers breached a heat-and-power plant facility in Poland, which supplies heat to about 50,000 residents, using a private APN (Access Point Name) to access an OT (Operational Technology) network. The reporting underscores the importance of treating third-party software and infrastructure as part of your own attack surface, since trust in a vendor is only as strong as the vendor’s own security posture. Beyond patching, organizations should inventory exposed services, disable unused functionality, and require multi-factor authentication wherever it can be deployed.
