Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Fast and Furious Tokyo Drift Han Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + uninstall/install URL hijack — classic monetization shell pattern replacing every new tab.
• Privacy policy is Google's own policy (scope_extension=false, data_collection=true, third_party_sharing=true) — does not cover this extension.
• No content security policy on MV3 extension with innerHTML DOM sinks — XSS attack surface.
• No developer name listed despite verified_publisher; install/uninstall redirects expose tracking behavior.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party redirect).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=tokyodrift&utm_medium=install.
• privacy_policy_generic store Policy URL is Google Account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension with DOM sinks.
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js — DOM-XSS risk without CSP.
• no_developer_name store developer_name is empty string despite verified_publisher=true.
• manifest_placeholders manifest manifest_name=__MSG_appName__ and manifest_description=__MSG_appDesc__ obscure true identity in store.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Fast and Furious Tokyo Drift Han Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.27 -> 6.77 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Search API enables search-provider influence; medium risk in NewTab context.
• host_permissions: https://api.gameograf.com/* medium Scoped to dev's own API domain; used for wallpaper/data fetches.
• chrome_url_overrides.newtab high NewTab override replaces every new tab — prime real estate for monetization and data collection.
