Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Forza Horizon 6 Porsche Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking — clear monetization shell pattern.
• NewTab override replaces every new tab; privacy policy is Google's generic policy, not scoped to this extension.
• Gmail dev address with no business domain; free-webmail + no verified publisher triggers reputation floor.
• Privacy policy admits data collection and third-party sharing (Google's own policy) with no extension-specific scope — treated as worst-case disclosure.

Evidence

• uninstall_url_hijack crx setUninstallURL targets gameograf.com with UTM params — explicit monetization redirect on removal.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params — install-time traffic hijack confirmed.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab controlled by extension.
• privacy_policy_generic store Policy URL is Google's own account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_dev store Developer email yakupsaylan357@gmail.com; no business website; not verified publisher.
• external_hosts_mismatch crx JS contacts gameograf.com, instagram.com, netflix.com, youtube.com, x.com — unexplained for a wallpaper extension.
• no_csp manifest content_security_policy is null; MV3 strict default applies but no explicit CSP declared.
• monetization_shell_pattern store Install+uninstall hijack + newtab override + utm tracking = classic low-effort traffic-monetization shell.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Forza Horizon 6 Porsche Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.12 -> 8.62 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; medium risk on its own but combined with newtab override elevates concern.
• chrome_url_overrides.newtab high Replaces every new tab with extension-controlled page; primary monetization vector for wallpaper shells.
