Dynamic Malicious Skills in Agentic AI (opens in new tab)

Skills are a key enabling component of agentic AI. While they enhance agents' capabilities, they also introduce new attack surfaces. In this work, we investigate one such attack surface by demonstrating dynamic malicious skills. By embedding malicious instructions in natural-language documentation (e.g., SKILL.md), an attacker can induce an agent to dynamically inject malicious logic into an otherwise benign skill during execution. We evaluate t...
