Top Risks

• Uninstall URL hijack to owhit.com and install URL hijack to owhit.com — classic traffic-monetization shell pattern.
• Privacy policy is Google's own account policy, not scoped to this extension; admits data collection and 3rd-party sharing — triggers +10 privacy.
• New-tab override paired with 'search' permission and free-webmail dev (gmail) with no verified business entity.
• 7 external JS hosts including social/AI platforms beyond stated wallpaper function; no CSP on MV3.
• Free-webmail developer with no publisher verification and a throwaway-style numbered alias email.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; classic monetization shell fingerprint.
• install_url_hijack crx onInstalled opens https://owhit.com/range-rover-wallpaper; traffic harvesting on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab redirected through extension.
• privacy_policy_generic store Policy URL is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true) — not scoped to extension.
• free_webmail_dev store Developer email yilmaztuna934@gmail.com — numbered alias, no verified business, no publisher badge.
• external_js_hosts crx 7 external hosts: owhit.com, chatgpt.com, instagram.com, youtube.com, x.com, google.com, chrome.google.com — broad beyond wallpaper function.
• no_csp manifest content_security_policy is null on MV3; no explicit CSP declared.
• search_permission_newtab_combo manifest 'search' permission + newtab override enables search monetization without declared search provider override.

Permissions Breakdown

• search medium Allows search provider query/manipulation; medium-risk in isolation but combined with newtab override is concerning.
• chrome_url_overrides.newtab medium Replaces every new tab with extension's index.html; high-reach monetization surface.
