What our analysis found

USO Chrome Extension (Chrome Manifest V3), used by 200,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can inject scripts into pages. It comes from a publisher with 6 extensions and was last updated in November 2025.

Analyst notes

The extension is a legitimate enterprise Single Sign-On tool (USO by i-Sprint). All permissions and API usage directly support its stated purpose: native messaging for local client communication, scripting.executeScript for credential injection into pages, and broad host permissions for SSO across any site. No external network requests, obfuscation, or covert data collection were found. The risk-engine and ML signals are typical false positives for this well-established, publisher-verified extension.
