The extension is a legitimate HTML5 skiing game exported with the Construct 2 engine. It declares zero permissions in (confirmed against the published manifest summary — no mismatch), so it cannot access any user data, browser history, tabs, or cookies. The background service worker () only performs two standard behaviors: opening the publisher's own [domain withheld] page on first install and setting an uninstall redirect — both pointing exclusively to the publisher's own domain. The ML score of 0.81 was driven by, which is explicitly labelled 'Generated by Construct 2, the HTML5 game and app creator' and is standard minified game engine output that naturally produces high exclamation-mark counts, XMLHttpRequest calls for asset loading, and large file sizes — none of these constitute malicious behavior. Third-party risk from chrome-stats independently confirms impact and likelihood, and the extension holds a CWS Featured badge. Publisher reputation is concerning ( other extensions flagged as malicious), but that context does not override the evidence in this extension's own code, which contains no exfiltration, no remote code loading, and no capability to harm users given the absence of any permissions.
