Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Minato And Naruto Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy (not scoped to this extension) yet admits data collection and 3rd-party sharing — scores maximum privacy risk.
• NewTab override with uninstall/install URL hijack to gameograf.com — classic monetization shell pattern.
• No CSP declared on MV3 extension with innerHTML DOM-XSS sink in popup.js.
• No developer name provided; verified publisher badge partially mitigates but 15-month staleness caps discount.

Evidence

• privacy_policy_generic store Privacy URL is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true) — +10.0 privacy pillar per v3.5 rule D.
• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=gameograf... — +3.0 webstore.
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=install... — +2.0 webstore.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html — +2.0 webstore (newtab override with monetization shape).
• dom_xss_sink crx popup.js: popupContainer.innerHTML = html — DOM-XSS sink with no CSP; +2.0 code quality (FIX B).
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension with innerHTML sink.
• stale_extension store 15 months since update — +6.0 maintenance; verified-publisher discount capped at -1.0 (>18mo threshold not met but staleness noted).
• verified_publisher store verified_publisher=true reduces reputation; cap applied: months_since_update=15 (<18), no CVEs, domain resolves — full discount applies.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Minato And Naruto Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.33 -> 7.83 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search provider interaction; combined with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited surface.
• chrome_url_overrides.newtab medium Replaces new tab page — high visibility, monetization/data capture surface.
