A critical vulnerability, dubbed EchoLeak, was discovered in Microsoft's Copilot that allowed attackers to exfiltrate data from emails and Microsoft SharePoint with zero clicks. The exploit bypassed security measures by embedding malicious instructions in emails, which Copilot would then execute when prompted, leading to data exfiltration through an allowlisted Teams preview endpoint. While Microsoft has since patched the vulnerability, the incident highlights the significant security risks associated with AI agents that have access to sensitive code and data, emphasizing the need for robust capability confinement and least privilege principles.
