Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Heart Love Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — persistent monetization/search-redirect surface.
• Uninstall and install URL hijack: both redirect to gameograf.com tracking URLs.
• No CSP on MV3 extension with innerHTML DOM sinks — DOM-XSS risk elevated.
• No developer name listed; verified publisher status partially mitigates but not fully.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — controls every new tab page.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=gameograf... (3rd-party tracking).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install... (3rd-party tracking URL).
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit extension-page CSP declared.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js — DOM-XSS sinks without CSP guard.
• verified_publisher store Verified publisher badge present; domain resolves, not throwaway.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• maintenance_stale store 12 months since last update — 6-12mo band adds +3.5 to maintenance pillar.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Heart Love Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.30 -> 6.80 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk in context of NewTab override.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization surface, search hijack vector.
