Top Risks

• Uninstall URL hijack to owhit.com and install URL hijack — classic traffic-monetization shell pattern.
• NewTab override combined with 'search' permission enables persistent search/ad-inject opportunity.
• Privacy policy is Google's generic account policy, completely unscoped to this extension — admits data collection and third-party sharing.
• Free-webmail dev (gmail) with generic developer name 'backgrounds', no verified publisher, no business website.
• JS contacts 8 external hosts (owhit.com, YouTube, Instagram, Netflix, OpenAI, X, etc.) with no CSP — opaque NewTab telemetry surface.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets https://owhit.com/uninstall — 3rd-party domain, +3.0 Webstore.
• install_url_hijack crx onInstalled opens https://owhit.com/hello-kitty-classroom-live-wallpaper/ — 3rd-party redirect, +2.0 Webstore.
• newtab_override manifest chrome_url_overrides.newtab = index.html replaces every new tab for 733 users.
• generic_privacy_policy store Policy URL is Google's own account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 Privacy (v3.5 D).
• free_webmail_developer store Developer email dermanseven32@gmail.com with generic name 'backgrounds', no verified publisher.
• js_external_hosts crx 8 external JS hosts including owhit.com, chat.openai.com, netflix.com, instagram.com with no CSP.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit restriction on connect-src.
• search_permission_newtab manifest 'search' permission paired with newtab override on a wallpaper extension — functionality mismatch.

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for a NewTab wallpaper extension.
• chrome_url_overrides.newtab high Replaces every new-tab page with extension-controlled HTML; high monetization/tracking potential.
