Top Risks

  • Operator cluster of 9 sibling extensions under same dev email — mass deployment pattern with WhatsApp access.
  • Uninstall URL hijack and install URL hijack both set — traffic manipulation on install/uninstall.
  • Privacy policy is Google's generic policy (not scoped to this extension) admitting data collection and 3rd-party sharing.
  • WhatsApp brand impersonation by unverified developer (extensao.store) — not a confirmed Meta partner.
  • 11 external JS hosts (wascript.com.br, watools.com.br) contacted from WhatsApp Web context — broad exfil surface.

Evidence

  • operator_cluster_siblings api 9 sibling extensions share same dev email, install URL, and JS host fingerprint — coordinated deployment cluster.
  • uninstall_url_hijack crx chrome.runtime.setUninstallURL() called; install_url_hijack also true — traffic hijack on lifecycle events.
  • brand_impersonation store WhatsApp brand mentioned; developer extensao.store is not confirmed Meta owner — is_impersonation=true.
  • generic_privacy_policy api Policy URL is myaccount.google.com/privacypolicy — not scoped to ZappyGO; data_collection=true, third_party_sharing=true.
  • js_external_hosts crx 10+ external hosts under wascript.com.br/watools.com.br contacted from WhatsApp Web content script context.
  • function_constructor crx new Function() found in bundled JS — dynamic code execution risk, +2.5 code quality.
  • dom_sink_innerhtml crx innerHTML assigned from variable in content script with no CSP — DOM-XSS sink elevated by missing CSP.
  • no_csp manifest content_security_policy is null (MV3 default applies but no explicit CSP); amplifies code findings.

Permissions Breakdown

  • unlimitedStorage low Allows unbounded local storage; moderate concern for CRM data hoarding.
  • storage low Standard key-value storage; low risk alone.
  • alarms low Scheduled background tasks; low risk.
  • tabs medium Can read tab URLs and metadata across browser; moderate risk.
  • https://web.whatsapp.com/* medium Scoped host access to WhatsApp Web; reads/manipulates all WhatsApp DOM and data.
