Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Assis Hub [data-theft] + malext.io malicious_extension_sentry (+2.5, capped).
• Cookie + WhatsApp host access: can exfiltrate WhatsApp session tokens and messages.
• Privacy policy is Google's own policy — not scoped to this extension at all (+10.0 privacy).

• new Function() constructor in app.js enables dynamic code execution.

Evidence

• cookies + whatsapp host manifest cookies permission + https://web.whatsapp.com/* host: full session/message read capability.
• privacy policy generic store Policy URL is myaccount.google.com/privacypolicy — Google's policy, not extension-scoped.
• dom_sink_innerhtml_userctrl x3 crx innerHTML sinks in app.js, background.js, contentScript.js with no CSP to mitigate XSS.
• function_constructor crx new Function() in app.js allows runtime code construction.
• no CSP manifest content_security_policy is null; no mitigation for eval or innerHTML sinks.
• free webmail dev store Developer email larzinho11@gmail.com; no verified publisher badge.
• external JS hosts crx js_external_hosts: notiflix.github.io, reactjs.org — remote CDN references in JS.
