Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Izuku Midoriya Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission = search monetization shell pattern; uninstall/install URL hijack confirmed.
• Privacy policy is Google's generic policy — does NOT scope to this extension; admits data collection and 3rd-party sharing.
• Two unmitigated innerHTML DOM-XSS sinks with no CSP present, increasing exploit surface.
• No developer name listed in store; verified publisher status provides limited accountability signal.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab with developer-controlled page.
• 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
• generic_privacy_policy store Privacy URL is Google's own policy (myaccount.google.com/privacypolicy) — scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink_no_csp crx innerHTML sinks in popup.js and calendar.js with csp_present=false — no mitigation in place.
• no_developer_name store developer_name field is empty; only email support@gameograf.com is listed.
• search_permission_newtab_combo manifest 'search' permission + newtab override is a recognized search-monetization pattern on low-install extension (511).
• verified_publisher store Extension carries verified_publisher=true; domain resolves and is not throwaway — partial trust signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Izuku Midoriya Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.47 -> 7.97 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can manipulate search provider; combined with newtab override raises monetization risk.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary vector for ad/search monetization shells.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
