Top Risks

• Uninstall URL hijack to owhit.com and install URL hijack — textbook monetization-shell pattern.
• Privacy policy is Google's own account policy: not scoped to this extension, admits data collection & 3rd-party sharing.
• Free-webmail developer (gmail) with no verified business — accountability gap.
• NewTab override combined with 'search' permission creates ad-redirect capability.
• External JS hosts include owhit.com, social platforms, and chatgpt.com — broad reach from a 281-install wallpaper extension.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets https://owhit.com/uninstall — monetization shell indicator (+3.0 Webstore).
• install_url_hijack crx onInstalled opens https://owhit.com/ive--wallpaper — 3rd-party install redirect (+2.0 Webstore).
• privacy_policy_generic store Policy URL is Google Account policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 Privacy.
• newtab_override manifest chrome_url_overrides.newtab=index.html replaces new-tab page; scored under Permissions per v2 rule (a).
• free_webmail_dev store Developer email canb08898@gmail.com; numbered alias pattern, no verified business — Reputation floor 7.5.
• js_external_hosts crx 7 external hosts: owhit.com, chatgpt.com, instagram.com, youtube.com, x.com, chrome.google.com, google.com.
• no_verified_publisher store verified_publisher=false, is_featured_by_google=false — no trust signals from Google.
• csp_absent_mv3 manifest content_security_policy=null; MV3 has strict default so no additional network penalty, but no CSP declared.

Permissions Breakdown

• search medium Allows search-provider manipulation; medium risk on its own but paired with newtab override raises concern.
• chrome_url_overrides.newtab medium Replaces new-tab page entirely; classic monetization vector when combined with install/uninstall URL hijacks.
