Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Space Portal Blue Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension; data collection and 3rd-party sharing admitted without extension context.
• NewTab override with install/uninstall URL hijacking to gameograf.com — monetization shell pattern.
• No CSP on MV3 extension with innerHTML DOM-XSS sink in popup.js.
• No developer name listed; verified publisher but identity accountability reduced.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new tab with extension page.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=gameograf — 3rd-party redirect on uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install — traffic capture on install.
• generic_privacy_policy api Privacy URL is Google's own policy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension with DOM sink.
• dom_xss_sink crx js/popup.js: popupContainer.innerHTML = html — user-controlled DOM sink, no CSP guard.
• no_developer_name store developer_name is empty string; reduced identity accountability despite verified_publisher=true.
• verified_publisher store verified_publisher=true with resolving domain gameograf.com; partial reputation credit applied.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Space Portal Blue Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.84 -> 7.34 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; medium risk in NewTab context.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; bounded surface.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary mechanism for search monetization.
