Microsoft Copilot (Microsoft 365): In Copilot Pages, the Chat can now be used to modify the Page

🚨 The Signal: Copilot Chat can now directly modify Microsoft 365 Pages. This increases the risk of unauthorised content changes or data leakage if prompts are not carefully managed, impacting data integrity and governance.

The Impact

All users interacting with Copilot and Pages are affected, increasing the risk of unintended content modification or data exposure.

• End-users: Risk of accidental data modification via imprecise prompts.
• Content Owners: Increased risk of unauthorised content changes to critical Pages.
• Security Teams: New vector for data integrity and exfiltration concerns via agentic actions.
• Compliance Teams: New audit trail requirements for AI-driven content changes.

The Action

1. Review and update existing Copilot data governance policies to include Page modification.
2. Educate users on responsible prompting practices for content modification.
3. Monitor Copilot activity logs for unusual Page modification patterns.
4. Assess existing Microsoft Purview Data Loss Prevention (DLP) policies for Copilot interactions with Pages.
