Top Risks

• Uninstall URL hijack AND install URL hijack both present — classic monetization/tracking shell pattern.
• Privacy policy is Google's generic policy (scope_extension=false, data_collection=true, third_party_sharing=true) — worst-case privacy score.
• WhatsApp brand impersonation by unverified developer (confirmed_owner=false).
• 10 distinct external JS hosts across wascript.com.br/watools.com.br — broad backend surface on WhatsApp CRM.
• function_constructor (new Function()) found in 4 files — dynamic code execution risk with no CSP.

Evidence

• js_external_hosts crx 10 distinct external hosts under wascript.com.br and watools.com.br contacted by extension JS.
• function_constructor x4 crx new Function() constructor found in 4 separate JS files; dynamic code execution without CSP.
• dom_sink_innerhtml_userctrl crx innerHTML assigned from variable in content JS running inside WhatsApp Web — DOM-XSS risk.

• developer_domain store Developer email contato@extensao.store; domain age ~992 days, 59 certs — not throwaway but unverified.
