Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Mercedes AMG F1 Cars Wallpapers New Tab Gameograf [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy (scope_extension=false, data_collection=true, third_party_sharing=true) — worst-case generic policy disclosure.
• Uninstall and install URL hijacks redirect users to gameograf.com tracking URLs on every install/uninstall cycle.
• NewTab override with search permission gives persistent reach over every browser session for monetization.
• No CSP declared (MV3 default applies but no explicit policy) with innerHTML DOM-XSS sink in popup.js.

Evidence

• privacy_policy_generic store Policy URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true — worst-case generic policy.
• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets https://gameograf.com/?utm_source=uninstall — 3rd-party tracking on removal.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install — install event used for traffic monetization.
• newtab_override_with_search manifest chrome_url_overrides.newtab + search permission: persistent reach over every new tab for search monetization.
• dom_xss_sink crx innerHTML written from variable in js/popup.js without CSP guard — DOM-XSS risk if variable is attacker-influenced.
• no_developer_name store developer_name is empty string; reduces accountability despite verified_publisher=true.
• stale_extension store months_since_update=15; falls in 12-24 month band (+6.0 maintenance score).
• external_host_mlionltd_github_io crx js_external_hosts includes mlionltd.github.io — third-party GitHub Pages host not explained by stated function.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Mercedes AMG F1 Cars Wallpapers New Tab Gameograf [adware] + malext.io malicious_extension_sentry; score 5.48 -> 7.98 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; paired with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; consistent with newtab functionality.
• chrome_url_overrides.newtab medium Replaces every new tab — high reach, monetization vector for ad/search revenue.
