Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Super Mario Bros Classic (+2.0, capped).
• Uninstall URL hijack present — sends users to 3rd-party destination on removal.
• Install URL hijack opens play.html on installation — unsolicited page load.
• Privacy policy admits data collection and 3rd-party sharing but is not scoped to this extension.
• eval() on user-controlled input and new Function() constructor enable arbitrary code execution.

Evidence

• uninstall_url_hijack crx uninstall_url_hijack=true; target=null. Extension registers an uninstall URL redirect.
• install_url_hijack crx install_url_hijack=true; target=play.html. Opens page on install.
• eval_user_input crx mario/ui.js: eval(x) where x is derived from onclick variable — arbitrary JS execution risk.
• function_constructor crx mario/editor.js: new Function(editor.rawfunc) executes raw user/map data as code.
• privacy_policy_scope_mismatch store Policy fetched; scope_extension=false, data_collection=true, third_party_sharing=true — admits sharing without extension scope.
• developer_identity store dev email adschallenges20xx@gmail.com (free webmail), developer_name empty, no business domain.
• verified_publisher store verified_publisher=true but discounts capped: free-webmail dev, monetization URL hijacks present.
• no_permissions_high_install_surface crx 56 JS files scanned, no declared permissions. v3.5-B anomaly: crx with no permissions but observable code surface.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Super Mario Bros Classic; score 4.55 -> 6.55 (+2.0 cap 2.5).
