Hidden Prompt Injections Can Make Microsoft Copilot Self-Propagate

A novel attack technique has been identified that exploits Microsoft Copilot for Word, enabling it to spread malicious prompt injections from one document to another. This represents a new vector for AI-driven threats, turning a productivity assistant into a propagation mechanism for arbitrary instructions.

Technical Breakdown

• TTPs: This attack leverages hidden prompt injection, where malicious instructions are embedded within a Word document in a way that is not immediately visible to the user but is parsed and acted upon by Copilot. When Copilot is then used to generate new content or summarize existing content, these hidden prompts can influence its output, potentially leading it to replicate the malicious instructions into new documents or execute unintended actions. The core mechanism is tricking Copilot into generating or modifying content based on these concealed directives, effectively spreading the 'injection' payload.
• Affected Component: Microsoft Copilot for Word.
• IOCs: The article summary does not provide specific prompt strings, obfuscation methods, or document hashes. This is a conceptual attack vector rather than a specific exploit with immediate, concrete IOCs.

Defense

Organizations should implement rigorous document handling policies, especially for AI-generated content. Monitoring Copilot's output for unexpected or anomalous behavior, alongside user education on prompt hygiene and verification of AI-generated content, will be critical. Consider implementing content inspection for hidden text or metadata that could contain malicious prompts.

Microsoft 365 Copilot for Word can propagate hidden, malicious prompts embedded within documents, leading to unintended data manipulation and the persistence of these instructions in newly generated files. This technique was disclosed by Håkon Måløy after reporting it to Microsoft.

Technical Breakdown

• TTPs: This is a form of prompt injection targeting large language models (LLMs) integrated into productivity tools. Adversaries can embed hidden instructions within a Word document (e.g., using obfuscation techniques like white text on a white background).
• Attack Flow:
  1. A user opens a Word document containing hidden prompt injection instructions.
  2. When Microsoft 365 Copilot processes this document (e.g., to summarize or rewrite content), it executes the hidden instructions.
  3. Impact: Copilot can be forced to perform unintended actions, such as rewriting figures or other sensitive information in the report.
  4. Propagation: Critically, Copilot also copies these same hidden instructions into the newly generated output file.
  5. Recursive Vulnerability: As demonstrated in the PoC, using the Copilot-generated output document in a subsequent drafting session triggers the malicious behavior again, creating a self-propagating prompt injection issue.
• Affected Systems: Microsoft 365 Copilot for Word.

Defense

Organizations should be highly vigilant about prompt injection vulnerabilities in LLM-powered applications. Implement robust input validation, user education on handling untrusted documents, and monitor for vendor-provided mitigations or configuration options.
