Microsoft Copilot Studio: Streamlining experiences from Copilot Studio Agents in Microsoft 365 Copilot

🚨 The Signal: Copilot Studio agents now integrate more smoothly with Microsoft 365 Copilot Chat, improving user experience with consistent formatting and interactive features. This change enhances agent usability but requires vigilance over agent permissions and data access.

The Impact

All users interacting with Copilot Studio agents are affected, with a security risk related to uncontrolled data access and potential for prompt injection.

• End users: Risk of unintended data exposure if agents are over-privileged.
• Security teams: Increased surface area for prompt injection and data exfiltration via agent interactions.
• Admins: Need to review and restrict agent permissions to sensitive data sources.
• Compliance teams: Potential for non-compliance with data handling policies if agent access is not governed.

The Action

1. Review all Copilot Studio agent configurations for data source access and permissions.
2. Implement least privilege principles for all agent identities and connectors.
3. Establish a robust prompt engineering and validation process for agent interactions.
4. Monitor agent activity logs for unusual data access patterns or prompt injection attempts.
5. Educate users on responsible interaction with AI agents and reporting suspicious behavior.
