Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Ryu vs. Ken Street Fighter Aduket [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission — classic search-monetization shell; uninstall and install URL hijacks to gameograf.com confirm monetization intent.
• Privacy policy is Google's generic account policy (scope_extension=false, data_collection=true, third_party_sharing=true) — admits data collection with no extension-specific scope.
• Uninstall URL hijack to gameograf.com tracking UTM and install URL hijack both confirmed — aggressive user tracking.
• No developer name listed; verified publisher status partially mitigated but 15-month stale update triggers invariant 0c cap on discount.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL points to 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 policy URL is Google's account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension with innerHTML sink.
• dom_xss_sink crx js/popup.js uses innerHTML assignment from variable — DOM-XSS sink without CSP protection.
• stale_update store Last updated June 2025; months_since_update=15, triggering 6-12mo maintenance band and 0c cap on VP discount.
• no_developer_name store developer_name is empty string; reduces accountability despite verified_publisher=true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Ryu vs. Ken Street Fighter Aduket [adware] + malext.io malicious_extension_sentry; score 5.72 -> 8.22 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows modifying search settings; combined with newtab override is a monetization vector.
• chrome_url_overrides.newtab medium Replaces new-tab page; standard shell pattern for search monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited reach.
