Chinese hackers are sabotaging key infrastructure in Australia, spy chief warns

Hackers working for the Chinese military and government have been probing Australia’s key infrastructure and telecoms network, warns spy chief.

Mike Burgess, director-general of security for the Australian Security Intelligence Organisation, warned Australians could have their water and electricity supplies cut off as well as extensive banking trouble if hackers managed to cause widespread telecoms disruption.

"Foreign governments have elite teams investigating these possibilities right now," Mr Burgess insisted.

However, China's foreign ministry accused Burgess's statement of spreading false narratives.

The warning demonstrates the difficulty faced by Australian prime minister Anthony Albanese in trying to keep China close economically while trying to mitigate security concerns.

Burgess said espionage was estimated to have cost the country A$12.5bn (£6.2bn) last year, including billions in trade secrets and intellectual property.

In particular, he highlighted the activities of the Chinese hacking groups Salt Typhoon and Volt Typhoon.

He highlighted how Salt Typhoon had previously penetrated US telecoms systems intending to disrupt operations and pre-position for potential sabotage.

Burgess also warned that Australian companies could be crippled as trade competitors or that elections could be affected.

Chinese officials made complaints to the Australian government and private sector about ASIO whenever he spoke
publicly about China, Burgess said during a speech last week. "It won't stop my resolve," he said.

Not the first time alarms have been raised

Concerns were raised in Canberra in February after Chinese warships conducted live-fire drills with minimal warning in the Tasman Sea.

Australian authorities only heard about the drills when a commercial pilot for Virgin Australia notified Airservices Australia.

The drills resulted in 49 flights having to change their path.
