Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Invincible War Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension; data_collection+third_party_sharing admitted without extension-level disclosure.
• NewTab override replaces every new tab; install and uninstall URL hijacks redirect to gameograf.com tracking URLs.
• No developer name listed; months_since_update=16 triggers v3.5 invariant 0c cap on verified-publisher discount.
• DOM-XSS sink (innerHTML from variable) in popup.js with no CSP present elevates code quality risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html — replaces every new tab page; primary monetization surface.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• privacy_policy_generic api Policy URL is Google's account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js; no CSP present — elevated DOM-XSS risk.
• no_developer_name store developer_name is empty string; verified_publisher=true but 0c cap applies: months_since_update=16 >15.
• stale_extension store 16 months since update; maintenance pillar=6.0 (6-12mo band boundary exceeded).
• search_permission_newtab_combo manifest search permission + newtab override together enable search provider monetization on every new tab.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Invincible War Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.34 -> 7.84 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override creates search monetization surface.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab — persistent high-reach surface for content injection and ad monetization.
