Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Corrupted Azir Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — not scoped to this extension; admits data collection and 3rd-party sharing (→ Privacy 10.0).
• NewTab override replaces every new tab with monetization surface; install+uninstall URL hijacks to gameograf.com.
• Two unmitigated DOM-XSS innerHTML sinks (popup.js, calendar.js) with no CSP in MV3 extension.
• No developer name listed; no 'Offered by' identity; newtab override paired with search permission.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all 9 users.
• privacy_policy_generic store Policy URL is Google's own privacy policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 Privacy.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install.
• dom_xss_sink_no_csp crx innerHTML used in popup.js and calendar.js with no CSP; DOM-XSS risk without content_security_policy mitigation.
• no_developer_name store developer_name is empty string; reduces accountability; verified_publisher=true partially mitigates.
• verified_publisher store verified_publisher=true — reputation discount applied but capped due to generic privacy policy.
• search_permission_newtab_combo manifest 'search' permission + newtab override = classic search monetization pattern on NewTab extensions.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Corrupted Azir Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.21 -> 7.71 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search provider interaction; paired with newtab override amplifies search monetization risk.
• host_permission: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab high Replaces every new tab — high reach, monetization surface, search hijack vector.
