Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Digital Art Skeleton Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — persistent high-reach monetization/redirect surface.
• Uninstall URL hijack redirects to gameograf.com with UTM tracking on removal.
• Install URL hijack opens gameograf.com on installation — traffic monetization pattern.
• No CSP (csp_present=false) on MV3 extension with innerHTML sinks — DOM-XSS exposure.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html — every new tab is owned by this extension.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=extension&utm_medium=install.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install.
• dom_xss_sinks crx innerHTML assigned from variables in js/popup.js and js/calendar.js with no CSP guard.
• no_csp manifest content_security_policy is null; MV3 default exists but no explicit CSP hardening.
• verified_publisher store gameograf.com verified publisher; resolves=true, not throwaway.
• privacy_policy api Policy fetched, scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; reduces accountability.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Digital Art Skeleton Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.93 -> 5.43 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; combined with NewTab override raises monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab — high-reach hijack surface for traffic monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain; limited blast radius.
