Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Venom The Last Dance 8K LiveWallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall + install URL both hijacked to gameograf.com — confirmed monetization shell pattern.
• New-tab override with free-webmail dev and no scoped privacy policy — generic Google policy used.
• Privacy policy is Google's own policy (scope_extension=false, admits data collection & 3rd-party sharing) — worst-case privacy score.
• Free-webmail developer (gmail) with no verified business; elevated-risk identity signals.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → gameograf.com with UTM params; monetization shell confirmed.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params; dual-hijack monetization pattern.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new-tab page replaced by extension.
• privacy_policy_generic store Policy URL is Google's own privacy page; scope_extension=false, data_collection=true, 3rd_party_sharing=true.
• free_webmail_developer store Developer email halilseker3455@gmail.com; no verified business domain; numbered-alias pattern.
• js_external_hosts crx gameograf.com, instagram.com, netflix.com, youtube.com, x.com contacted — 5 unrelated external domains.
• search_permission_plus_newtab manifest search permission + newtab override = search-hijack capability despite no explicit search override declared.
• no_csp crx content_security_policy is null; MV3 strict default applies but no explicit CSP hardening.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Venom The Last Dance 8K LiveWallpaper [adware] + malext.io malicious_extension_sentry; score 5.40 -> 7.90 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading and modifying search provider; combined with newtab override raises search-hijack risk.
• chrome_url_overrides.newtab high Replaces every new-tab page; primary monetization surface for ad/tracking injection.
