Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kuromi Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall + install URL both hijacked to gameograf.com ad-tech domain — textbook monetization shell.
• NewTab override replaces every new-tab; privacy policy is generic Google policy, not scoped to this extension, admits 3rd-party sharing.
• Free-webmail developer (gmail), no developer name, no business website; accountability near zero.
• JS contacts instagram.com, netflix.com, youtube.com, x.com from a wallpaper extension — far beyond stated function.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → gameograf.com with UTM tracking params; classic monetization shell.
• install_url_hijack crx onInstalled opens gameograf.com with matching UTM params; redirects user on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new-tab page replaced by extension.
• external_hosts_mismatch crx JS contacts gameograf.com, instagram.com, netflix.com, youtube.com, x.com — unrelated to wallpaper function.
• privacy_policy_generic store Policy URL is Google's own privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_no_devname store Developer email halilseker3455@gmail.com; developer_name empty; no verifiable business identity.
• verified_publisher_cap_applied store verified_publisher=true but monetization hits (gameograf.com) trigger v3.5 invariant 0c; discount capped at -1.0.
• search_permission_plus_newtab manifest search permission + newtab override = search-monetization surface even without search override declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kuromi Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.14 -> 8.64 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying/intercepting browser search; paired with newtab override = search monetization surface.
• chrome_url_overrides.newtab high Replaces every new-tab page; prime monetization and data-collection vector.
