Microsoft Copilot (Microsoft 365): Copilot in Loop available in Loop components in Teams and Outlook

🚨 The Signal: Copilot can now generate content within Loop components when pasted into Teams, Outlook, and Meeting Notes. This expands AI-driven content creation, increasing potential for data exposure and prompt injection risks.

The Impact

All Copilot users are affected, increasing the risk of sensitive data exposure and malicious prompt injection through AI-generated content.

  • Copilot users: Increased risk of unintentional data exposure in shared Loop components.
  • Security teams: New vectors for prompt injection attacks via Loop components.
  • Compliance teams: Greater challenge in monitoring and governing AI-generated content.
  • Data owners: Potential for sensitive information to be surfaced by Copilot in shared contexts.

The Action

  1. Review and reinforce Microsoft Purview Data Loss Prevention (DLP) policies for Loop components.
  2. Educate users on responsible Copilot use, especially regarding sensitive data in prompts.
  3. Monitor Copilot usage logs for unusual activity or data access patterns.
  4. Implement sensitivity labels for Loop components to classify and protect data.
  5. Regularly review Copilot access and license assignments to ensure least privilege.
