In this episode of the Security Swarm Podcast, the host Andy Syrewicze and the guest Philip Galea discuss the security implications of Microsoft’s AI assistant Copilot, which is integrated into the Microsoft 365 suite. They explore how Copilot’s ability to surface information from an organization’s Microsoft 365 data can create significant security risks, especially for companies that lack the operational maturity to properly manage permissions and access controls.
The discussion also covers Microsoft’s reactive approach to security in some of its products, where default settings are often not secure enough, and the company is slow to address these issues. The host and the guest emphasize the need for organizations to take a proactive approach to security, continuously reviewing and updating their security posture to mitigate the risks posed by Copilot and other Microsoft 365 features.
The episode also introduces Hornetsecurity’s Tenant Manager tool, which aims to help organizations better manage and enforce their Microsoft 365 security settings, providing a centralized and automated way to ensure that their environments are configured according to best practices.

Key Takeaways:
-
Copilot makes it easy for nosy or malicious insiders to quickly surface sensitive information that they may not have proper access to.
-
Copilot could be abused by threat actors who compromise a user account with an active Copilot license, allowing them to easily gather intelligence and move laterally within the organization.
-
Microsoft’s default security settings and permissions in Microsoft 365 are often too open, creating challenges for organizations to properly secure their data.
-
Jailbreaking Copilot to bypass its security restrictions is an ongoing concern, as it could allow users to access restricted information.
-
Solutions like sensitivity labels and disabling search on sensitive SharePoint sites have significant drawbacks and may not be practical for many organizations.
-
Tools like Hornetsecurity’s Permission Manager and Tenant Manager can help organizations better manage and enforce security policies across Microsoft 365.
-
Continuous security awareness and training for employees is crucial to mitigate the risks posed by Copilot and other AI-powered tools.
