🔴 Critical | Source: The Register — Security
Nation-state threat actors have successfully compromised critical Australian infrastructure, embedding access designed to enable disruptive attacks at a time of their choosing. The Australian intelligence community identified at least one separate operation in progress and coordinated with foreign counterparts to neutralise it before it could cause harm. This represents a significant escalation in state-sponsored pre-positioning within essential services.
Security Architect’s Take: Audit your OT/IT network segmentation and verify that critical infrastructure control systems cannot be reached from cloud-connected environments; implement assume-breach monitoring with behavioural baselines so dormant persistent access is detectable before adversaries activate it.
Original advisory: Nation-state actors cracked critical Australian infrastructure to ‘cripple it at a time of their choosing’
