Microsoft Copilot Studio: Conversational configuration of connectors in Copilot Studio

🚨 The Signal: Copilot Studio now allows conversational configuration of connectors, simplifying agent integration with external services. This introduces a new vector for unauthorised data access if not properly governed, bypassing traditional admin controls.

The Impact

Admins and Security Teams are affected by increased risk of unauthorised data access and exfiltration via Copilot agents.

• Security Teams: Risk of data exfiltration via misconfigured or malicious Copilot agents.
• Admins: New attack surface to monitor and secure within Copilot Studio.
• End Users: Potential for social engineering if agents are compromised.
• Data Owners: Increased risk of sensitive data exposure through agent connections.

The Action

1. Review and update Copilot Studio data loss prevention (DLP) policies to restrict connector usage.
2. Implement granular access controls for Copilot Studio environments and connector creation.
3. Monitor Copilot Studio audit logs for unusual connector configurations or data access patterns.
4. Educate Copilot Studio creators on secure connector configuration and data handling best practices.
5. Establish a formal review process for all new Copilot agent deployments and connector integrations.
