Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Formula 1 redbull car F1 champion [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com with tracking UTM params — clear monetization shell.
• NewTab override combined with 'search' permission enables search-traffic monetization on every new tab.
• Developer name (Dekuy.com) mismatches email domain (gameograf.com) — identity inconsistency.
• DOM XSS sinks (innerHTML from variable) found in popup.js and calendar.js with no CSP to mitigate.

Evidence

• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy — 3rd-party tracking redirect.
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy — monetization on install.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new-tab page with developer-controlled content.
• developer_identity_mismatch store developer_name=Dekuy.com but email=support@gameograf.com; privacy policy served from api.gameograf.com.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP present to mitigate DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening for inline DOM sinks.
• search_permission_newtab_combo manifest 'search' permission + newtab override = classic search-monetization pattern on low-install themed extension.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true — adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Formula 1 redbull car F1 champion [adware] + malext.io malicious_extension_sentry; score 4.09 -> 6.59 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows query of search providers; paired with newtab override enables search monetization.
• 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; monetization vector; high daily-use surface.
