Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Fortnite Doublecross Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Fortnite brand impersonation: developer (haberikra.com) is not Epic Games — confirmed impersonation flag.
• NewTab override with install/uninstall URL hijack — classic monetization shell; tracks install/removal via UTM parameters.
• No developer name listed; brand impersonation by unofficial third party without verified ownership.
• Extension is 14 months stale (6-12mo band) with no changelog, increasing future-compromise risk.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true for 'fortnite'; developer domain haberikra.com not confirmed as Epic Games.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with UTM tracking params — monetization shell signal.
• install_url_hijack crx onInstalled opens gameograf.com with UTM install tracking — monetization shell signal.
• no_developer_name store developer_name is empty string; no 'Offered by' identity visible to users.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js with csp_present=false — DOM-XSS risk.
• stale_extension store months_since_update=14; falls in 12-24mo band (+6.0 maintenance).
• privacy_policy api Policy fetched, scoped, discloses data collection, retention, and third-party sharing — adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Fortnite Doublecross Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.28 -> 7.78 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading search provider settings; paired with newtab override elevates risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer-controlled API domain only.
• chrome_url_overrides.newtab medium Replaces every new tab — high reach, monetization vector for NewTab shells.
