Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Excalibur Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL both hijack to gameograf.com with UTM tracking — classic monetization shell pattern.
• Privacy policy is Google's generic policy (scope_extension=false, data_collection=true, third_party_sharing=true) — worst-case Privacy score.
• NewTab override + search permission enables search provider hijacking and ad-tech monetization.
• Free-webmail developer (gmail) with no business website or verified publisher badge; throwaway identity.

Evidence

• uninstall_url_hijack manifest setUninstallURL → gameograf.com with UTM params; classic monetization shell.
• install_url_hijack manifest onInstalled opens gameograf.com with identical UTM tracking params.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab for all users.
• privacy_policy_generic store Policy is Google's own account policy — scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_dev store Developer email poyrazkareyel735@gmail.com; numbered alias pattern; no business domain.
• external_hosts_mismatch crx JS contacts instagram.com, netflix.com, youtube.com, x.com — inconsistent with wallpaper function.
• search_permission_newtab_combo manifest search + newtab override enables search provider hijacking for ad-monetization.
• csp_absent_mv3 manifest content_security_policy is null; no CSP declared despite external JS host list.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Excalibur Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.49 -> 7.99 (+2.5 cap 2.5).
