Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Satoru Gojo Hollow Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override: replaces every new-tab page, persistent monetization/tracking surface.
• Uninstall and install URL hijacking to gameograf.com UTM campaign links.
• DOM-XSS sink (innerHTML from variable) in popup.js with no CSP to mitigate.
• Stale extension: 15 months since update increases risk of unpatched issues.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html — replaces every new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL to gameograf.com UTM campaign link — traffic monetization signal.
• install_url_hijack crx onInstalled opens gameograf.com UTM install link — monetization shell pattern.
• dom_sink_innerhtml_userctrl crx popup.js assigns innerHTML from variable without CSP; DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• stale_15mo store Last updated June 2025 — 15 months since update, elevated abandonment risk.
• verified_publisher store Verified publisher badge present; discount applied but capped at -1.0 (stale >18mo threshold not yet met, applies partial).
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true — adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Satoru Gojo Hollow Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 3.44 -> 5.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Access to search query data; medium risk for a NewTab/wallpaper extension.
• host_permission:https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; prime monetization surface and persistent user exposure.
