Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Solo Leveling with Sung Jin-Woo Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension at all; admits data collection and 3rd-party sharing (score: 10.0).
• Newtab override replaces every new tab + uninstall/install URL hijack to gameograf.com UTM tracking (monetization shell pattern).
• Two DOM-XSS sinks (innerHTML from variables) with no CSP; MV3 default strict but no explicit CSP declared.
• No developer display name on listing despite verified publisher; reduced trust signal.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; every new tab hijacked; combined with 'search' permission.
• uninstall_url_hijack crx setUninstallURL -> https://gameograf.com/?utm_source=gameograf&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg&utm_content=install
• privacy_policy_generic store Policy URL is Google's own privacy policy (myaccount.google.com/privacypolicy) — not scoped to this extension.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP to mitigate.
• no_developer_name store developer_name is empty string despite verified_publisher == true.
• verified_publisher store verified_publisher == true; reputation discount applied but capped due to generic policy and monetization URL pattern.
• new_tab_monetization crx Wallpaper/NewTab shell with UTM-tracked install+uninstall hooks; classic low-install traffic-monetization pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Solo Leveling with Sung Jin-Woo Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.92 -> 7.42 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search behavior; combined with newtab override amplifies search monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab page; high-reach persistent monetization surface.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
