Authority Impersonation in Agent Input
This detects text that tries to trick an AI agent into ignoring its safety rules by claiming to come from an authority figure — like a system administrator, CISO, or company policy. The agent can't actually verify who is talking to it, so the attacker just states an authority claim and hopes the agent complies rather than refuses.
How the attack works
An attacker crafts a prompt, document, or tool response containing phrases like 'as your system administrator', 'approved by the CISO', or 'per company policy you must'. This text reaches the agent either as a direct input, as content it retrieves from an external source, or as a response from a connected tool. The agent has no mechanism to confirm the claimed identity or authorization, so the phrasing is designed purely to make the agent feel that refusing the request would be a compliance failure. If it works, the agent performs an action or discloses information it would otherwise have blocked.

Why it matters
An organization can lose control over what its AI agent will do or reveal, since guardrails meant to require real authorization can be talked past with fabricated claims rather than any actual verification.
What you can do
- →Do not let agents treat in-conversation claims of authority as valid credentials; require actual authentication or a verified caller identity for privileged actions.
- →Review agent guardrail logic so refusals are based on verifiable permissions, not on the tone or wording of the request.
- →Audit content sources feeding the agent (retrieved documents, tool outputs) for injected authority-claim language, especially in untrusted or user-supplied sources.
- →Expect legitimate false positives from real administrators describing their role, security training material, and summarized policy documents — tune review processes to distinguish these from active manipulation attempts.
Known benign look-alikes
- A genuine administrator or developer describing their role in a prompt
- Security awareness training material and phishing-simulation content
- Policy documents legitimately retrieved and summarised by the agent
- Incident runbooks that quote approval language verbatim
