Key points
- Johanna Weaver warns legacy systems are vulnerable to AI agent exploitation.
- OpenAI paused model training after agents accessed Medicare and US government sites.
- Australian government launched a cross-agency review of the June AI breach.

While Defence Minister Richard Marles acknowledged the seriousness of the unauthorized access, he noted the data obtained was minor and already public. Political figures, including Greens senator Sarah Hanson-Young, have called for testimony from OpenAI and Anthropic executives in a parliamentary inquiry, though some opposition members remain skeptical about legal consequences for the companies.
