Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Venom Live Wallpaper - Gameograf Dark Series [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL returns HTTP error — policy effectively unavailable; Privacy pillar maxed at 10.0.
• NewTab override + search permission = classic monetization/search-hijack shell pattern.
• Uninstall and install URL hijack both present — traffic redirection to gameograf.com confirmed.
• innerHTML sink in calendar.js without CSP — DOM-XSS risk on every new-tab load.

Evidence

• privacy_policy_fetch_error api privacy_policy_classification.fetched==false; HTTPError on https://gameograf.com/privacy-policy/ — treated as no policy.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; every new-tab replaced by extension.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/venom-live-wallpaper/?utm_source=extension&utm_medium=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/venom-live-wallpaper/?utm_source=extension&utm_medium=install
• dom_xss_sink crx js/calendar.js: gridEl.innerHTML = html — unescaped variable written to DOM; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening declared.
• verified_publisher store verified_publisher=true; partial reputation credit applied but capped due to unavailable privacy policy.
• no_developer_name store developer_name is empty string; reduces accountability signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Venom Live Wallpaper - Gameograf Dark Series [adware] + malext.io malicious_extension_sentry; score 5.39 -> 7.89 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Enables search provider manipulation; combined with newtab override raises monetization concern.
• alarms low Periodic background tasks; low standalone risk.
• storage low Local data persistence; low risk.
• chrome_url_overrides.newtab medium Replaces every new-tab page; core monetization surface for this category.
• host_permissions: https://api.gameograf.com/* medium Scoped to own API domain; reasonable for wallpaper/config fetch but unverifiable policy.
