Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — DOOM The Dark Ages Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission = classic search-monetization shell; install + uninstall URL hijacks confirmed.
• Privacy policy is Google's generic policy (not scoped to this extension), yet data_collection and third_party_sharing are true — scores as worst-case.
• Uninstall and install URL hijacking to gameograf.com tracking URLs — behavioral monetization evidence.
• External JS host mlionltd.github.io is an uncontrolled third-party GitHub Pages domain — supply-chain risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces new-tab page entirely.
• install_uninstall_hijack manifest Both onInstalled and uninstall URLs redirect to gameograf.com with UTM tracking params.
• generic_privacy_policy store Privacy policy URL is Google's own account policy — not scoped to this extension; data_collection+third_party_sharing true.
• external_uncontrolled_host crx js_external_hosts includes mlionltd.github.io — third-party GitHub Pages, not developer-controlled.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit restriction declared.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js with no CSP guard — DOM-XSS risk.
• search_permission_newtab_combo manifest search permission + newtab override = monetization-pattern fingerprint.
• stale_16mo store Last updated May 2025; months_since_update=16 → maintenance score elevated.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — DOOM The Dark Ages Wallpapers [adware] + malext.io malicious_extension_sentry; score 5.57 -> 8.07 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows override of browser search; paired with NewTab override amplifies search-monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for ad/search monetization.
