Top Risks

• Uninstall AND install URL hijack both point to owhit.com — classic monetization shell pattern (+6.0 Webstore).
• Privacy policy is Google's generic account policy, not scoped to this extension — admits data collection & 3rd-party sharing (+10.0 Privacy via v3.5 rule D).
• New-tab override with search permission enables search monetization with no transparency.
• Free-webmail developer (gmail), no verified publisher, no business domain — low accountability.
• No CSP on MV3 extension with external JS hosts including social/AI platforms.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; 3rd-party tracking/monetization on removal.
• install_url_hijack crx onInstalled opens https://owhit.com/tokyo-revengers-wallpaper; 3rd-party engagement on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new-tab page for monetization.
• generic_privacy_policy store Privacy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email bulenttuncer250@gmail.com; no verified publisher badge; no business domain.
• external_js_hosts crx JS references owhit.com, chatgpt.com, instagram.com, x.com, youtube.com — unrelated to wallpaper function.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension.
• new_tab_with_search_override manifest search permission + newtab override = search monetization surface without user disclosure.

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for search hijacking.
• chrome_url_overrides.newtab high Replaces new-tab page; high monetization and data-capture surface per v2 rule (a).
