Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Killua Hunter X Hunter Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + search permission enables search hijacking and ad-monetization on every new tab.
• Privacy policy is Google's generic policy — not scoped to this extension; admits data collection and third-party sharing.
• Uninstall URL hijack and install URL hijack to gameograf.com UTM links — monetization-shell behavior.
• No CSP declared (MV3 default applies); innerHTML sinks in popup.js and calendar.js raise DOM-XSS risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• 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
• generic_privacy_policy api Privacy URL is Google's account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP to mitigate.
• no_developer_name store developer_name is empty string; reduces accountability.
• search_permission_newtab_combo manifest search permission + newtab override = classic search-monetization shell pattern.
• low_install_newtab store 737 installs with newtab+search override; tail-attack-surface risk if extension is sold/transferred.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Killua Hunter X Hunter Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.44 -> 7.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Search API access; combined with newtab override enables search hijacking.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach monetization surface with search override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
