Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — One Piece Beach Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab with developer-controlled content; high-reach monetization vector.
• Google's generic privacy policy used — not scoped to this extension; admits data collection and third-party sharing.
• Uninstall and install URL hijacks redirect users to gameograf.com tracking URLs.
• Two innerHTML DOM-XSS sinks with no CSP — content from api.gameograf.com could be injected into newtab page.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — every new tab hijacked.
• privacy_policy_generic store Privacy policy points to Google's own policy (myaccount.google.com); scope_extension=false, data_collection=true, third_party_sharing=true.
• 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_sinks crx innerHTML assigned from variables in popup.js and calendar.js with no CSP — DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit restriction on connect-src.
• verified_publisher store Developer has verified publisher badge; domain gameograf.com resolves and is not throwaway.
• search_permission_plus_newtab manifest search permission + newtab override is classic search-monetization shell pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — One Piece Beach Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.20 -> 7.70 (+2.5 cap 2.5).
