Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Breaking Bad Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab page — core search/monetization hijack surface.
• Privacy policy is Google's generic account policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• Uninstall and install URL hijacks redirect users to developer site with UTM tracking.
• No CSP declared (MV3 default only); innerHTML DOM-XSS sink in popup.js compounds risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — controls every new tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• privacy_policy_generic api Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; reduces accountability signal.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js with no CSP to mitigate DOM-XSS.
• stale_extension store 15 months since last update; maintenance risk elevated.
• verified_publisher store Publisher verified but no featured badge; cap applies due to months_since_update>18 not met (15mo), but generic policy limits discount.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Breaking Bad Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.50 -> 7.00 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can read/manipulate search queries; higher risk paired with newtab override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer-owned API domain; limited blast radius.
• chrome_url_overrides.newtab high Replaces every new tab; high-visibility monetization surface, search-hijack vector.
