Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — God of War Ragnarök Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + search permission enables persistent ad/redirect monetization on every new tab.
• Uninstall and install URL hijacks track user lifecycle via UTM parameters to gameograf.com.
• Extension contacts 10 external JS hosts (incl. mlionltd.github.io) with no CSP to constrain them.
• 16 months since last update — stale for an active newtab product.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to index.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=uninstall&utm_medium=link&utm_campaign=bg
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg
• broad_external_js_hosts crx 10 external JS hosts including mlionltd.github.io, chatgpt.com, instagram.com, netflix.com, reddit.com.
• no_csp manifest content_security_policy is null; no CSP restricts script sources in MV3 extension pages.
• stale_extension store Last updated May 2025 but months_since_update=16; newtab products require frequent updates.
• verified_publisher store Developer is verified publisher at gameograf.com which resolves and is not a throwaway domain.
• privacy_policy_adequate api Policy fetched, scoped to extension, discloses data collection, retention, and third-party sharing.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — God of War Ragnarök Wallpapers [adware] + malext.io malicious_extension_sentry; score 4.58 -> 7.08 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; paired with newtab override elevates monetization risk.
• chrome_url_overrides.newtab medium Replaces every new tab — high-reach persistent surface for ad/redirect monetization.
