Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Luffy Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override installs on every browser new-tab open, giving persistent reach to all users.
• Uninstall and install URL hijacks redirect users to gameograf.com tracking URLs (monetization shape).
• Two innerHTML DOM-XSS sinks found (popup.js, calendar.js) with no CSP present to mitigate exploitation.
• No developer name listed despite verified publisher; developer identity partially opaque.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• install_uninstall_url_hijack crx Both install and uninstall URLs redirect to gameograf.com with UTM tracking params.
• dom_xss_sink_no_csp crx innerHTML sinks in popup.js and calendar.js with csp_present==false amplifies XSS risk.
• no_developer_name store developer_name is empty string; reduces accountability despite verified_publisher==true.
• verified_publisher store Extension carries verified publisher badge; partial reputation credit applied.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_install_count store Only 24 installs — community scrutiny absent; tail attack surface.
• no_csp manifest content_security_policy is null for MV3 extension; no additional CSP hardening.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Luffy Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.06 -> 6.56 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk for a NewTab override extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab; high reach even with no other broad host permissions.
