Top Risks

• Uninstall URL hijack to owhit.com and install URL hijack — classic NewTab monetization shell pattern.
• Privacy policy is Google's generic account policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• New-tab override + search permission with free-webmail dev and no developer name — low accountability.
• JS external hosts include chatgpt.com, instagram.com, netflix.com, youtube.com, x.com — broad reach from a wallpaper extension.
• No developer name supplied; free-webmail (gmail) developer with no business domain identity.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets https://owhit.com/uninstall — 3rd-party monetization domain.
• install_url_hijack crx onInstalled opens https://owhit.com/kuromi-wallpaper — 3rd-party domain on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new-tab page for all users.
• generic_privacy_policy store Privacy policy is Google's account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_no_dev_name store Developer email nermincandas@gmail.com; developer_name is empty; no business domain.
• broad_js_external_hosts crx JS references chatgpt.com, instagram.com, netflix.com, youtube.com, x.com — excessive for a wallpaper extension.
• search_permission_newtab manifest search permission + newtab override combination is a known NewTab ad-monetization pattern.
• no_csp manifest content_security_policy is null; MV3 provides strict default but no explicit policy declared.

Permissions Breakdown

• search medium Allows overriding search provider; combined with newtab override is a monetization signal.
• chrome_url_overrides.newtab high Replaces new-tab page entirely; primary mechanism for ad-monetization NewTab shells.
