Threat SnapshotSource: Dragos

Ransomware group targets Australian energy operator

A known threat actor has added an Australian energy utility to its leak site following a suspected OT network intrusion. Operations were not disrupted but data exfiltration is confirmed.

Impact

SOCI Act mandatory notification obligations are likely triggered, requiring the operator to report to CISC within 12 hours of becoming aware of the incident.

Action Required

Review your incident notification playbook now and confirm your designated CISC reporting contact — do not wait for a breach to locate this information.

Essential Eight maturity guidance updated for OT environments

The ACSC has revised its Essential Eight guidance with new notes on applying application control and patching in operational technology contexts.

Impact

Operators running legacy SCADA systems now have clearer guidance on patching exemption criteria, which affects how you document and justify your current maturity level.

Action Required

Review the updated patching exemption criteria against your existing OT asset register and update your Essential Eight self-assessment before your next compliance review.

Critical vulnerability disclosed in widely-used PLC firmware

A remotely exploitable flaw has been disclosed in a PLC line common in water and mining sites. No public exploitation has been confirmed yet, but a vendor patch is available.

Action Required

Confirm whether your asset register includes the affected PLC model, schedule a maintenance window to apply the vendor patch, and isolate the device from external networks in the interim.
