AgentDojo-Inspect is a codebase created by the U.S. AI Safety Institute to facilitate research into agent hijacking and defenses against said hijacking. Agent hijacking is a type of indirect prompt injection [1] in which an attacker inserts malicious instructions into data that may be ingested by an AI agent, causing it to take unintended, harmful actions.AgentDojo-Inspect is a fork of the original AgentDojo repository [2], which was created by researchers at ETH Zurich [3]. This fork extends the upstream AgentDojo in four key ways:1. It adds an Inspect bridge that allows AgentDojo evaluations to be run using the Inspect evaluations framework [4] (see below for more details).2. It fixes some bugs in the upstream AgentDojo's task suites (most of these fixes have been merged upstream). It also removes certain tasks that are of low quality.3. It adds new injection tasks in the Workspace environment that have to do with mass data exfiltration (these have since been merged upstream).4. It adds a new terminal environment and associated tasks that test for remote code execution vulnerabilities in this environment.[1] Greshake K, Abdelnabi S, Mishra S, Endres C, Holz T, Fritz M (2023) Not what you?ve signed up for: Compromising Real-World LLM-Integrated Applications with Indirect Prompt Injection (arXiv), arXiv:2302.12173. https://doi.org/10.48550/arXiv.2302.12173[2] Edoardo Debenedetti (2025) ethz-spylab/agentdojo.
