Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Futuristic Bedroom Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack — classic monetization/traffic-capture shell pattern.
• Privacy policy URL returns HTTP error (fetch_error); effective privacy policy is absent, scoring maximum risk.
• Uninstall and install URL hijacks redirect to developer domain with UTM tracking on every install/remove.
• NewTab + search permission combo enables default-search monetization; search_engine_count=1 but pattern matches ad-aggregator fingerprint.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; every new-tab captured.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?p=32988?utm_source=extension&utm_medium=uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com/?p=32988?utm_source=extension&utm_medium=install.
• privacy_policy_fetch_error api privacy_policy_classification.fetched==false due to HTTPError; policy effectively unavailable.
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• developer_name_missing store developer_name is empty string; no 'Offered by' attribution shown.
• verified_publisher store verified_publisher==true; partial reputation credit but no featured badge.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Futuristic Bedroom Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.41 -> 7.91 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser's default search; combined with newtab override raises monetization risk.
• alarms low Schedules periodic tasks; low standalone risk.
• storage low Local data persistence; low risk.
• chrome_url_overrides.newtab high Replaces every new-tab page; primary monetization/data-capture surface for this category.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer API; low blast radius but all new-tab data flows here.
