Top Risks

• Privacy policy is Google's own policy — not scoped to this extension; admits data collection and 3rd-party sharing (→ Privacy +10.0).
• Uninstall URL hijack and install URL hijack both present; classic monetization/tracking shell pattern.
• WhatsApp brand impersonation by unverified developer 'ewdht' on extensao.store.
• 10+ distinct external wascript.com.br / watools.com.br endpoints contacted from content script on WhatsApp Web.
• function_constructor (new Function) + innerHTML DOM-XSS sink in content scripts running on WhatsApp chat.

Evidence

• uninstall_url_hijack + install_url_hijack manifest Both hijack flags true; install redirects to web.whatsapp.com — monetization/tracking shell indicators.
• privacy_policy_generic_google store Policy URL is myaccount.google.com/privacypolicy — not scoped to this extension; data_collection+third_party_sharing true.
• brand_impersonation_whatsapp store brand_mention.is_impersonation=true; developer extensao.store is not confirmed WhatsApp/Meta owner.
• js_external_hosts_count crx 10 distinct wascript.com.br / watools.com.br external hosts; broad outbound surface from WhatsApp content script.
• function_constructor crx new Function() in content script — dynamic code execution risk on WhatsApp DOM.
• dom_sink_innerhtml_userctrl crx innerHTML from variable in content script; no CSP present, elevates DOM-XSS risk.
• no_csp_mv3 manifest csp_present=false; MV3 default applies but no explicit CSP hardens against innerHTML/new Function findings.
• developer_identity_weak store Developer name 'ewdht' is opaque; not verified publisher; not featured; no recognized org.

Permissions Breakdown

• unlimitedStorage low Allows unlimited local storage; minor risk, no data exfil by itself.
• storage low Standard local key-value store; low risk.
• alarms low Scheduling API; low risk, used for automation timing.
• tabs medium Can read tab URLs/titles; moderate risk when combined with WhatsApp host access.
• https://web.whatsapp.com/* medium Scoped host permission to WhatsApp Web; allows full DOM read/write on chat interface.
