The threat of cyber attacks on Australia’s energy industry and infrastructure is rising, a new report has found, with the sector breaking into the top 10 most attacked rankings in 2022. According to the annual threat report from cyber spy outfit the Australian Signals Directorate, there was a cluster of strikes on energy companies and infrastructure in 2022, in amongst the major cyber attacks on Medibank, Optus and others that dominated news headlines. Energy Australia outed itself in October, AGL in December, and the Australian Signals Directorate (ASD) says an unnamed energy provider was also attacked but its existing security worked as intended. The hacking risk to Australia’s evolving energy infrastructure is growing, experts say. Indeed, the electricity sector broke into the top 10 most attacked industries for the first time in 2021-22, according to the ASD. But to date the widening array of technologies from virtual power plants to Internet of things sensors haven’t been the security risk long feared – even in the US people who want to bring down the grid are preferring physical over cyber attacks.
