Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Charmander Pokemon Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override: controls every new tab page, enabling search/ad monetization redirect.
• Uninstall & install URL hijack both active — traffic monetization pattern confirmed.
• No CSP declared (MV3); innerHTML sinks in popup.js and calendar.js elevate DOM-XSS risk.
• No developer name listed; extension title uses Pokemon IP without verified brand ownership.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; controls every new tab for all users.
• 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=extension&utm_medium=install.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• dom_xss_sink crx innerHTML sinks in js/popup.js and js/calendar.js without CSP mitigations.
• no_developer_name store developer_name is empty string; accountability gap.
• verified_publisher store verified_publisher == true; partial reputation credit but no featured badge.
• privacy_policy_adequate api Policy fetched; scope_extension, data_collection, retention, third_party_sharing all true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Charmander Pokemon Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.90 -> 5.40 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser's default search engine; medium risk in context of NewTab override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; expected for wallpaper/newtab data fetching.
• chrome_url_overrides.newtab medium Replaces every new tab — high REACH for monetization or search redirect.
