(Updated) Microsoft Teams: Meeting notes now available for instant meetings

🚨 The Signal: Teams instant meetings now support Loop-powered notes, enabling real-time collaborative content creation. This expands the attack surface for data exfiltration and uncontrolled information sharing within the organisation.

The Impact

All users are affected by increased data sprawl and potential for sensitive information exposure through unmanaged collaborative notes.

• End users: Can inadvertently share sensitive data in Loop notes.
• Security team: Faces increased risk of data exfiltration and sprawl.
• Compliance team: Must address new vectors for uncontrolled information sharing.

The Action

1. Review and enforce Microsoft Purview DLP policies for Loop components to prevent sensitive data sharing.
2. Educate users on appropriate data handling and sharing practices for Loop components in Teams.
3. Monitor Microsoft 365 audit logs for Loop component sharing activities, especially with external users.
4. Configure Loop component sharing settings in the Microsoft 365 admin center to align with organisational data governance policies.
5. Assess existing information protection labels for applicability to Loop components and update as necessary.
