Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Satoru Gojo Breaking Glass Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack — classic monetization shell pattern
• No CSP on MV3 extension with innerHTML DOM-XSS sinks in popup.js and calendar.js
• search permission on NewTab allows search-query interception for monetization
• No developer name listed despite verified publisher badge

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; replaces every new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com with UTM tracking params — monetization signal.
• install_url_hijack crx onInstalled opens https://gameograf.com with UTM install tracking — monetization signal.
• no_csp manifest content_security_policy is null; no CSP declared on MV3 extension with innerHTML sinks.
• dom_xss_sinks crx Two innerHTML user-controlled assignments in popup.js and calendar.js without sanitization.
• search_permission_newtab manifest search permission combined with newtab override enables search-query capture.
• verified_publisher store Verified publisher badge present; developer domain gameograf.com resolves and is not throwaway.
• privacy_policy_adequate api Policy fetched, scoped to extension, covers data collection, retention, and third-party sharing.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Satoru Gojo Breaking Glass Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.07 -> 6.57 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading search queries; medium risk for a NewTab extension intercepting searches.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary surface for monetization or search hijacking.
