Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Star Wars Moving Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with install+uninstall URL hijacks to gameograf.com — classic traffic-monetization shell pattern.
• Privacy policy is Google's generic policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• Two DOM-XSS sinks (innerHTML from variables) with no CSP present — XSS risk on every new tab page.
• No developer name listed; verified publisher badge paired with generic Google privacy policy is misleading.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — controls every new tab for 366 users.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params — monetization redirect on install.
• uninstall_url_hijack crx setUninstallURL points to gameograf.com with UTM — tracking on uninstall.
• privacy_policy_generic api Policy URL is Google's own policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink_no_csp crx Two innerHTML sinks in popup.js and calendar.js; csp_present=false amplifies XSS risk.
• no_developer_name store developer_name is empty string; identity relies solely on email domain.
• verified_publisher store Verified publisher badge present but no featured badge; reputation partially mitigated.
• newtab_monetization_pattern manifest search permission + newtab override + UTM hijacks = standard traffic-monetization cluster.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Star Wars Moving Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.25 -> 7.75 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; paired with newtab override elevates risk.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer API; enables outbound data transfer to dev-controlled endpoint.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach surface for monetization or search hijack.
