Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Satoru Gojo: Unleash the Power of Jujutsu! Gameograf [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own generic policy — scope_extension=false, admits data collection and 3rd-party sharing; scores 10.0.
• No last_updated date available — maintenance scored at maximum (10.0); extension age unknowable.
• NewTab override with uninstall/install URL hijack to gameograf.com is a monetization-shell pattern.
• mlionltd.github.io in js_external_hosts is an unverified third-party GitHub Pages endpoint.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab is developer-controlled.
• uninstall_url_hijack crx setUninstallURL → gameograf.com with UTM params; classic monetization-shell signal.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params; install redirect.
• generic_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy — Google's policy, not developer's; scope_extension=false.
• no_last_updated store last_updated field is empty string; maintenance pillar cannot be scored below maximum.
• external_host_github_pages crx js_external_hosts includes mlionltd.github.io — unverified third-party endpoint.
• dom_xss_sink_no_csp crx innerHTML set from variable in popup.js; csp_present=false amplifies risk per FIX B.
• no_developer_name store developer_name is empty string; identity accountability reduced.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Satoru Gojo: Unleash the Power of Jujutsu! Gameograf [adware] + malext.io malicious_extension_sentry; score 5.57 -> 8.07 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search-provider interaction; paired with newtab override amplifies monetization surface.
• 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 with developer-controlled page; persistent monetization surface.
