Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Child Luffy in Winter Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab, high-reach monetization/tracking surface.
• Privacy policy URL is on a different domain (haberikra.com) and failed to fetch — effectively no policy.
• Uninstall and install URL hijacks redirect users to gameograf.com with UTM tracking.
• No developer name listed; privacy policy domain differs from developer domain — accountability gap.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for all 139 users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&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
• privacy_policy_unfetchable api Privacy policy at haberikra.com failed to fetch (HTTPError); different domain from developer; treated as no policy.
• no_developer_name store developer_name is empty string; accountability gap despite verified_publisher flag.
• dom_xss_sink crx js/popup.js uses innerHTML with variable input — DOM-XSS risk without CSP.
• no_csp manifest content_security_policy is null; no CSP protection for MV3 extension with DOM-sink finding.
• stale_15mo store Last updated June 10 2025 but months_since_update=15 indicates original scoring context; 12-24mo band applies.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Child Luffy in Winter Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.37 -> 7.87 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Search API can redirect or override search queries; medium concern paired with newtab override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; narrow but enables outbound data flow.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach monetization surface; scored per v2 calibration rule (a).
