Top Risks

• Uninstall and install URL both hijack to gameograf.com ad-campaign URL — confirmed monetization shell.
• NewTab override + search permission replaces every new tab and can redirect searches for ad revenue.
• Privacy policy is Google's generic policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• Free-webmail developer (gmail) with no verified business identity; throwaway-style dev profile.
• External JS hosts include major social/streaming sites (Instagram, Netflix, YouTube, X) — unexplained for a wallpaper.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → gameograf.com with utm_source=ovkas; confirmed monetization redirect.
• install_url_hijack crx onInstalled opens gameograf.com with same UTM params; classic game-portal monetization shell.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab captured by this extension.
• privacy_policy_generic store Policy URL is Google account privacy policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_dev store Developer email birolkaya63536@gmail.com; no business website; no verified publisher badge.
• js_external_hosts_unexplained crx JS contacts gameograf.com, instagram.com, netflix.com, youtube.com, x.com — unrelated to wallpaper function.
• search_permission_newtab_combo manifest search permission + newtab override enables full search monetization pipeline.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension.

Permissions Breakdown

• search medium Allows overriding search provider; paired with newtab override enables monetization of user searches.
• chrome_url_overrides.newtab high Replaces new-tab page; core mechanism for ad/monetization injection on every new tab open.
