Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Art Wallpapers New Tab [browser-hijack] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL unreachable (fetch error); no verifiable data-handling disclosure — treated as no policy.
• 35-month-stale NewTab extension with newtab override; near triple-stale threshold with no updates.
• new Function() constructor and eval() in bundled JS create code-injection risk on the new-tab surface.
• Free-webmail developer (artshappen00@gmail.com), no developer name — low accountability.
