Scarecrow: Making the Attacker’s AI Say No

Scarecrow is a defensive tool that embeds refusal instructions in documents to prevent artificial intelligence (AI) agents from processing them. The technique works by prompting AI agents to stop ingestion when they encounter these hidden directives, potentially disrupting unauthorized AI-driven access to sensitive data.

Why it matters: Security teams responsible for protecting sensitive documents can use this approach to limit exposure when AI agents or large language models attempt to extract information from confidential files.
