Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Naruto Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack — textbook monetization/tracking shell pattern.
• No developer name listed; verified publisher badge with empty identity field is a governance gap.
• Extension is 14 months stale; persistent newtab surface with no recent security maintenance.
• innerHTML DOM-XSS sink in popup.js with no CSP declared (csp_present=false).

Evidence

• uninstall_url_hijack manifest chrome.runtime.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
• newtab_override manifest chrome_url_overrides.newtab = newtab.html — full new-tab replacement by a wallpaper/fan-content shell.
• dom_xss_sink crx js/popup.js: innerHTML assigned from variable without sanitization; csp_present=false amplifies risk.
• no_developer_name store developer_name is empty string; no 'Offered by' display name despite verified_publisher=true.
• stale_extension store 14 months since last update; newtab override remains active across all user sessions.
• privacy_policy_adequate api Policy fetched, scoped to extension, discloses data collection, retention, and third-party sharing.
• no_csp manifest content_security_policy is null; MV3 strict default applies but no explicit CSP declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Naruto Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 4.08 -> 6.58 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Access to Chrome search API; relevant for NewTab but enables search-provider influence.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new tab page; high user-facing surface, monetization vector.
