Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Labubu Dance Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks every new tab; install+uninstall URL hijacks confirm monetization shell pattern.
• Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and 3rd-party sharing (→ Privacy pillar 10.0).
• No developer name listed; no 'Offered by' branding increases accountability gap.
• Two innerHTML DOM-XSS sinks with no CSP (csp_present=false) elevate code quality risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html — replaces every new tab with extension 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 store Privacy URL is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• no_developer_name store developer_name is empty string — no 'Offered by' accountability.
• dom_xss_no_csp crx 2x innerHTML sinks (popup.js, calendar.js) with csp_present=false — unmitigated DOM-XSS surface.
• new_tab_monetization_pattern manifest NewTab + search permission + install/uninstall URL hijack = classic traffic-monetization cluster.
• verified_publisher store verified_publisher=true for gameograf.com; domain resolves and is not throwaway — partial trust credit.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Labubu Dance Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.18 -> 7.68 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying default search engine; combined with newtab override amplifies search monetization risk.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer's own API; enables telemetry/data exfil to dev-controlled endpoint.
• chrome_url_overrides.newtab medium Replaces every new tab — high reach, monetization surface, search hijack vector.
