Queensland energy generator CS Energy said it was responding to a ransomware incident that occurred over the weekend.
In a brief statement on the matter released Tuesday, the company said that the attack, which took place on November 27, impacted its corporate IT network, but did not hinder electricity generation at its Callide and Kogan Creek power stations.
“CS Energy moved quickly to contain this incident by segregating the corporate network from other internal networks and enacting business continuity processes,” CS Energy’s CEO Andrew Bills said.
“We immediately notified relevant state and federal agencies, and are working closely with them and other cyber security experts.
“We have contacted our retail customers to reassure them that there is no impact to their electricity supply and we have been regularly briefing employees about our response to this incident.”
The company did not say what ransomware was involved in the attack, or what ransom the attackers demanded.
