CERT Polska issued mitigation guidance for private APNs used to reach OT equipment after a real intrusion path into a Polish CHP plant. The recommendations focus on client isolation, traffic segmentation, and default-credential hygiene to stop lateral movement across cellular-managed access. The guidance is aimed at reducing the risk of pivoting from a compromised device into industrial control systems.
