ASIO Says China-Linked Hackers Probed Australian Critical Infrastructure, Warns of Sabotage Risk

After ASIO’s alert, China lodged a formal denial as the agency pressed boards to harden systems.

Overview

  • Director‑General Mike Burgess named Salt Typhoon and Volt Typhoon as hackers working for Chinese government intelligence and the military.
  • ASIO said the groups probed Australian telecommunications and other critical networks and, in some cases, gained access as part of pre‑positioning for potential sabotage.
  • Burgess warned Australia has reached the threshold for high‑impact sabotage, citing targets across water, transport, energy and communications.
  • He referenced prior U.S. and Microsoft findings about Volt Typhoon’s stealthy footholds and Salt Typhoon’s telecom espionage as corroborating context.
  • ASIO urged companies to strengthen cyber governance, noting espionage cost A$12.5 billion in 2023–24 and estimating about A$1.1 billion per cyber‑sabotage incident.
