What our analysis found
Microsoft Single Sign On, used by 36,000,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in August 2024.
This is the legitimate Microsoft Single Sign-On extension (published by Microsoft Corporation, Google trusted publisher badge confirmed). The code is minimal and clean: establishes a postMessage channel (keyed on a fixed GUID) to bridge page-level SSO requests to the service worker, and forwards those requests to the native host 'com.microsoft.browsercore' — the standard Microsoft SSO broker. No data exfiltration, no obfuscation, no remote code loading. The ML score of 0.00 is already low; the risk-engine 'medium' rating is driven entirely by nativeMessaging and document_start execution, both of which are inherent to this extension's core SSO function.
