Improved capabilities for files with Copilot in OneDrive Web

🚨 The Signal: Copilot's advanced file analysis capabilities, previously in SharePoint, are now directly integrated into OneDrive Web. This allows users to interact with files using natural language, potentially increasing data exposure if permissions are not strictly managed.

The Impact

OneDrive users with Copilot licenses are affected, increasing the risk of unintended data exposure or exfiltration if access controls are not rigorously enforced.

• Copilot users: Enhanced data interaction capabilities increase risk of over-sharing or exfiltration.
• Admins: Need to review and potentially tighten OneDrive and SharePoint access controls.
• Security Teams: Must monitor for new data access patterns and potential policy violations.
• Compliance Teams: Requires re-evaluation of data handling and retention policies for AI-driven interactions.

The Action

1. Review existing OneDrive and SharePoint site permissions and sharing policies to ensure least privilege.
2. Audit Copilot usage logs for unusual data access patterns or summarization activities.
3. Communicate to users the importance of data sensitivity when interacting with Copilot in OneDrive.
4. Evaluate Microsoft Purview Data Loss Prevention (DLP) policies for Copilot interactions in OneDrive.
5. Consider implementing stricter sensitivity labels on highly confidential documents in OneDrive.
