Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — PRAXATECH SOLUÇÕES [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — does not scope to this extension; admits data collection and third-party sharing (Privacy +10.0).
• Operator cluster: 3 sibling extensions under same dev email/host fingerprint suggest coordinated deployment.
• Uninstall URL hijack and install URL hijack both present — classic monetization/tracking shell pattern.
• 10+ distinct external JS hosts under wascript.com.br / watools.com.br contacted by extension running inside WhatsApp Web.

Evidence

• uninstall_url_hijack + install_url_hijack crx Both hijacks set; install redirects to https://web.whatsapp.com. Monetization shell pattern.
• operator_cluster sibling_count=3 api Three sibling extensions share same dev email, install URL, and JS host set — coordinated cluster.

• developer identity weak store Dev name 'wspd'; email contato@extensao.store; not verified publisher, not featured.
• host_permissions scoped to WhatsApp Web manifest Content scripts injected into web.whatsapp.com/* — full access to all WhatsApp messages in browser.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — PRAXATECH SOLUÇÕES [adware] + malext.io malicious_extension_sentry; score 5.41 -> 7.91 (+2.5 cap 2.5).
