Planner: Planner Agent in Copilot V2 Improvements

🚨 The Signal: Copilot's Planner agent gains enhanced capabilities, including broader task assignment and improved context handling. This increases the potential for sensitive information exposure and unauthorized task management via AI.

The Impact

All users are affected, with increased risk of data exposure and unauthorized task manipulation through AI agent interactions.

  • End Users: Risk of inadvertently exposing sensitive task details to Copilot or unauthorized users.
  • Security Teams: Increased attack surface for prompt injection and data exfiltration via agent interactions.
  • Admins: Need to review and enforce data governance policies for AI agent interactions.
  • Compliance Teams: Challenges in auditing AI agent actions and ensuring data handling adheres to regulatory requirements.

The Action

  1. Review and update Microsoft 365 Copilot data governance policies to explicitly address agent interactions.
  2. Implement data loss prevention (DLP) policies to monitor and restrict sensitive information shared with Copilot agents.
  3. Educate users on secure prompting practices and the types of information suitable for AI agent interaction.
  4. Monitor Copilot audit logs for unusual activity related to task creation, assignment, and data access.
  5. Assess the impact of broader task assignment capabilities on existing role-based access controls (RBAC) for Planner.
