Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kiki’s Delivery Service Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own generic policy — not scoped to this extension, yet admits data collection and third-party sharing (Privacy +10.0).
• NewTab override with uninstall and install URL hijacks pointing to gameograf.com — classic monetization shell pattern (+2.0+2.0).
• 16 months since last update — stale but not zombie; moderate maintenance risk.
• No developer name listed; verified publisher flag offers partial mitigation but developer identity is thin.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to index.html — full new-tab replacement.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=uninstall&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• generic_privacy_policy store Privacy policy URL is Google's own account policy — scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML set from variable in js/popup.js; no CSP present on MV3 extension.
• no_developer_name store developer_name is empty string; verified_publisher=true partially mitigates.
• external_host_mlionltd_github_io crx js_external_hosts includes mlionltd.github.io — third-party GitHub Pages host not owned by developer.
• stale_update store Last updated May 27 2025, months_since_update=16 — maintenance risk (6.0 pillar).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kiki’s Delivery Service Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.36 -> 7.86 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can manipulate search queries; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-owned API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page — prime monetization surface.
