Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — WAME [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — not scoped to this extension; admits data collection and 3rd-party sharing.
• Uninstall and install URL hijack flags set; install redirects to web.whatsapp.com.
• WhatsApp brand impersonation by unconfirmed developer on extensao.store domain.
• 11 external JS hosts across wascript.com.br and watools.com.br; no CSP to constrain them.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true for 'whatsapp'; developer domain extensao.store is not Meta/WhatsApp.
• uninstall_url_hijack manifest uninstall_url_hijack=true; install_url_hijack=true targeting https://web.whatsapp.com.
• generic_privacy_policy store Privacy policy URL is Google's account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• external_js_hosts crx 10+ distinct wascript.com.br/watools.com.br endpoints in js_external_hosts; no CSP present.
• function_constructor crx new Function() constructor detected in content script JS; code execution risk.
• dom_xss_sink crx innerHTML assigned from variable; no CSP amplifies DOM-XSS risk.
• no_csp manifest content_security_policy=null; MV3 default applies but no explicit restriction on connect-src.
• low_installs_unverified_dev store Only 14 installs; not verified publisher; developer Intzp on extensao.store TLD.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — WAME [adware] + malext.io malicious_extension_sentry; score 5.43 -> 7.93 (+2.5 cap 2.5).
