Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Luffy and Zoro Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab; combined with search permission enables search-traffic monetization.
• Uninstall and install URL hijacks redirect users to gameograf.com via UTM tracking links.
• No developer name listed; developer identity accountability is weak despite verified publisher badge.
• DOM-XSS sink (innerHTML) in popup.js with no CSP present — exploitable if content is user-controlled.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to index.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=uninstall — 3rd-party tracking.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install — monetization fingerprint.
• dom_xss_sink crx js/popup.js: innerHTML assigned from variable; no CSP to mitigate DOM-XSS risk.
• no_developer_name store developer_name is empty string; accountability gap despite verified_publisher == true.
• stale_extension store 15 months since last update; newtab + search override combination left unmaintained.
• external_host_mlionltd crx js_external_hosts includes mlionltd.github.io — third-party github.io domain, unrelated to dev.
• verified_publisher store Verified publisher badge present; discounts reputation but capped due to monetization shape.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Luffy and Zoro Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.39 -> 6.89 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override elevates risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach surface for monetization or search hijacking.
