Double Agents: Defensive AI Agents Magnify Cyber Risks
Agencies considering AI agents for defensive cyber purposes face a demonstrated attack surface that could turn those tools against them.
Key points
- AI Now Institute research demonstrates a proof-of-concept exploit hijacking defensive AI agents built by Anthropic and OpenAI.
- The attack vector turns security-focused AI agents against their own users, enabling remote code execution.
- Directly relevant to APS agencies evaluating AI agents for cybersecurity or IT operations use cases.
Implications for Australian agencies
- Consider Agencies evaluating or piloting AI agents for cybersecurity, IT operations, or defensive monitoring could assess whether this attack vector applies to their intended deployment configurations.
- Monitor AI governance and security teams may want to monitor whether Anthropic and OpenAI issue mitigations or guidance in response to this research, and whether ACSC or AISI comment on agentic AI security risks.

New research from the AI Now Institute identifies a critical attack vector affecting AI agents built on Anthropic and OpenAI platforms when deployed for defensive cybersecurity purposes. A proof-of-concept exploit demonstrates that such agents can be hijacked and turned against their users, enabling remote code execution. The finding is accompanied by a policy brief with key takeaways. The research raises significant questions about the security of agentic AI systems in high-stakes operational contexts, including government cybersecurity environments.
Implications for Australian agencies:
- [Consider] Agencies evaluating or piloting AI agents for cybersecurity, IT operations, or defensive monitoring could assess whether this attack vector applies to their intended deployment configurations.
- [Monitor] AI governance and security teams may want to monitor whether Anthropic and OpenAI issue mitigations or guidance in response to this research, and whether ACSC or AISI comment on agentic AI security risks.
