Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Girl Biker From Cyberpunk Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack — classic traffic-monetization shell pattern.
• No CSP declared (MV3 default exists but csp_present=false in manifest); innerHTML sink in popup.js raises XSS risk.
• Stale 15 months (>12mo) with newtab override — abandoned monetization surface.
• No developer_name field; reduced accountability despite verified publisher badge.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for all users.
• uninstall_url_hijack manifest setUninstallURL -> https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_sink_innerhtml_userctrl crx js/popup.js: popupContainer.innerHTML = html — DOM-XSS sink with no CSP to mitigate.
• months_since_update store Last updated June 2025; 15 months stale — maintenance pillar +6.0.
• verified_publisher store Verified publisher badge present; -3.0 reputation discount applied.
• privacy_policy_classification api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true. Adequate.
• no_developer_name store developer_name field is empty string; reduced accountability signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Girl Biker From Cyberpunk Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.26 -> 6.76 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; medium risk for a NewTab override extension.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; narrows outbound access.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary surface for monetization/search injection.
