Microsoft Copilot (Microsoft 365): Agent Mode in Word for Enhanced document editing
🚨 The Signal: Copilot in Word gains 'Agent Mode,' allowing AI to edit documents based on chat interactions. This introduces new risks for data integrity, accidental disclosure, and prompt injection, requiring careful governance of AI agent actions.
The Impact
All users interacting with Copilot in Word are affected, increasing the risk of data manipulation, unintended information disclosure, and prompt injection vulnerabilities.
- End-users: Risk of unintended document changes or data exposure if prompts are not precise.
- Security Teams: Increased surface area for prompt injection attacks and data exfiltration via agent actions.
- Data Owners: Potential for AI to alter sensitive information without explicit human review.
- Compliance Teams: New challenges in auditing and ensuring data integrity and confidentiality.
The Action
- Review and update existing Microsoft 365 Copilot governance policies to include agent mode usage.
- Educate users on secure prompting techniques and the importance of reviewing AI-generated content.
- Monitor Copilot usage logs for unusual activity or potential prompt injection attempts.
- Implement data loss prevention (DLP) policies to prevent sensitive information from being processed or altered inappropriately by Copilot agents.
- Assess and configure Copilot access controls to limit agent mode to authorized users or data types.
