CS Energy, one of Australia’s largest energy producers, was the subject of a ransomware attack in late November. The exact target of the attack was its corporate networks, confirmed CEO Andrew Bills. Fortunately, CS Energy staff reacted quickly enough to prevent widespread damage – segregating affected networks to stop the spread of the attack further down the line. It also confirmed that energy production was not affected, and that it would be able to continue to supply customers as normal. This attack is the latest in a string of incidents targeting critical national infrastructure.
