Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Pusheen Using Laptop In Lofi Room Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — scope_extension=false, data_collection=true, third_party_sharing=true: worst-case privacy signal.
• NewTab override hijacks every new tab; combined with install+uninstall URL hijacks to gameograf.com (monetization funnel).
• Uninstall and install URL hijacks redirect to developer domain with UTM tracking parameters.
• Two unguarded innerHTML sinks (popup.js, calendar.js) with no CSP — DOM-XSS risk if API data is attacker-influenced.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab page.
• install_uninstall_url_hijack crx install→gameograf.com?utm_source=pusheen, uninstall→gameograf.com?utm_source=extension — monetization funnel.
• generic_privacy_policy api PP URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js with no CSP — DOM-XSS attack surface.
• no_developer_name store developer_name is empty string; no 'Offered by' identity visible in store.
• verified_publisher store verified_publisher=true, gameograf.com resolves, domain age 2051 days — partially mitigates reputation risk.
• search_engine_count_1 api Only google.com seen; single search engine, no multi-engine monetization aggregator pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Pusheen Using Laptop In Lofi Room Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.42 -> 6.92 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser search engine; relevant for NewTab but adds capability.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces every new tab; high reach, monetization surface.
