Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — The Recreation Room Inside the Aquarium Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks new-tab page for a low-install wallpaper with uninstall/install URL tracking.
• Uninstall and install URL hijacks fire analytics redirects to gameograf.com on every lifecycle event.
• No CSP present on MV3 extension with innerHTML DOM-XSS sink in popup.js.
• Extension stale 15 months; no ratings or user feedback to validate safety.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page for all sessions.
• uninstall_url_hijack crx setUninstallURL fires to gameograf.com with UTM params on uninstall.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params — lifecycle tracking.
• no_csp manifest content_security_policy is null; no CSP despite innerHTML sink in popup.js.
• dom_xss_sink crx popup.js uses innerHTML with variable input — DOM-XSS risk without CSP guard.
• maintenance_stale store Last updated June 2025 but months_since_update=15; 6-12 month band applies → +3.5.
• verified_publisher store Verified publisher badge present; discount applied but capped at -1.0 due to stale >12mo (v3.5 invariant 0c).
• privacy_policy_adequate api Policy fetched; scope_extension, data_collection, retention, third_party_sharing all true — fully scoped.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — The Recreation Room Inside the Aquarium Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.06 -> 6.56 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading search queries; medium risk in NewTab context.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization surface and user-facing override.
