Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Dodge Charger Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension; admits data collection and 3rd-party sharing (→ +10 privacy).
• New-tab override with uninstall URL hijack and install URL hijack — classic monetization shell pattern.
• No CSP on MV3 and DOM-XSS innerHTML sinks in popup.js and calendar.js without CSP protection.
• Developer name missing; verified publisher but privacy policy points to Google's account policy, not a developer-authored policy.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com/?utm_source=gameograf&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg&utm_content=install
• generic_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy — Google's own policy, not developer's; 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 innerHTML sinks.
• dom_xss_sinks crx innerHTML assigned from variable in js/popup.js and js/calendar.js without CSP guard — DOM-XSS risk.
• developer_name_missing store developer_name is empty string; verified_publisher true but no displayed dev name.
• maintenance_stale store months_since_update=12; falls in 6-12mo band (+3.5).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Dodge Charger Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.84 -> 7.34 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search — medium risk, enables search interception.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; prime real estate for monetization and data collection.
