Five Eyes warns AI accelerates cyber threats as Australia releases comprehensive threat assessment

The heads of the Five Eyes cyber security agencies issued a joint statement warning that artificial intelligence is now a real‑time weapon for attackers, compressing the window between vulnerability discovery and exploitation from weeks to days or even hours. The statement urged organisations to prioritise basic cyber‑defence practices, such as rapid patching and mature asset management, and to use AI to augment—not replace—these fundamentals.

In Australia, Director‑General of Security Mike Burgess presented his seventh annual threat assessment, describing a "concurrent, cascading and compounding" security environment. He cited a range of coordinated activities targeting Australians, including Iranian‑directed terrorism, foreign espionage through fabricated consulting personas, nation‑state hackers compromising critical‑infrastructure networks, and a long‑running foreign interference campaign.

Both assessments were described as inter‑linked, illustrating how the AI‑driven offensive capabilities highlighted by Five Eyes feed directly into the broader, offline threats outlined by Burgess. Officials stressed that closing the gap between discovery and mitigation, and strengthening cyber fundamentals, are essential to protect national resilience and social cohesion.
