Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Fortnite Gia Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Brand impersonation: uses 'Fortnite' in title; developer domain haberikra.com is not Epic Games.
• NewTab override with install/uninstall URL hijack to gameograf.com — classic monetization shell.
• No developer name listed; verified publisher identity is mismatched vs. brand claim.
• innerHTML DOM-XSS sink in popup.js with no CSP; could be exploited if API response is attacker-controlled.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true for 'fortnite'; confirmed_owner=false; dev domain haberikra.com ≠ epicgames.com.
• newtab_override manifest chrome_url_overrides.newtab=newtab.html — replaces every new tab, high-reach monetization surface.
• 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.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js; no CSP present; DOM-XSS risk if api.gameograf.com is compromised.
• no_csp manifest content_security_policy is null; MV3 default applies but dom_sink finding elevates risk without explicit policy.
• verified_publisher_with_stale store verified_publisher=true but months_since_update=14 and brand impersonation present; 0c cap applies, discount capped at -1.0.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true, third_party_silence=false.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Fortnite Gia Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.27 -> 7.77 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search engine; paired with newtab override creates search-monetization surface.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach monetization surface, classic NewTab shell pattern.
