Microsoft Copilot (Microsoft 365): Work context suggestions in Copilot Chat ContextIQ menu

🚨 The Signal: Copilot Chat will now suggest work context and prompts based on user access. This increases the risk of inadvertent data exposure if access controls are not rigorously enforced.

The Impact

All users are affected, increasing the risk of accidental data exposure through Copilot's enhanced content surfacing.

  • End users: May inadvertently access or be prompted with sensitive data if permissions are over-provisioned.
  • Security teams: Increased risk of data leakage if access controls are not strictly managed.
  • Admins: Must ensure least privilege is enforced to prevent unintended data exposure.

The Action

  1. Review and enforce least privilege access across all Microsoft 365 content sources.
  2. Utilize Microsoft Purview to identify and classify sensitive information.
  3. Implement Microsoft Purview Data Loss Prevention (DLP) policies to prevent sharing of sensitive data.
  4. Regularly audit user access to sensitive documents and sites.
  5. Educate users on responsible use of Copilot and data handling best practices.
