Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — NewJeans Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + Amazon affiliate link (amzn.to) in JS hosts = affiliate monetization shell.
• Uninstall and install URL hijacks route users to gameograf.com with tracking params.
• 18 months since last update — stale for an active newtab extension.
• No developer name listed; no featured badge; limited accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab page for all users.
• affiliate_hit crx js_external_hosts includes amzn.to — Amazon affiliate short-link per threat_intel.affiliate_hits.
• uninstall_url_hijack crx setUninstallURL targets gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking params.
• stale_extension store months_since_update=18; borderline zombie for a newtab/wallpaper extension.
• unknown_third_party_host crx mlionltd.github.io in js_external_hosts; purpose undisclosed; GitHub-hosted asset.
• no_developer_name store developer_name is empty; reduced accountability despite verified_publisher=true.
• verified_publisher store verified_publisher=true with resolving domain; partial reputation credit applied.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — NewJeans Wallpapers [adware] + malext.io malicious_extension_sentry; score 4.33 -> 6.83 (+2.5 cap 2.5).
