Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — RoboZapp [data-theft] + malext.io malicious_extension_sentry (+2.5, capped).
• Free-webmail dev (wl.exten.06@gmail.com) with WhatsApp brand impersonation confirmed.
• Privacy policy fetched but not scoped to this extension and data_collection=false — generic policy.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true for 'whatsapp'; developer domain is gmail.com, not Meta/WhatsApp.
• free_webmail_dev store Developer email wl.exten.06@gmail.com is free-webmail with numbered alias; no verified business domain.
• privacy_policy_generic api Policy fetched (hiperchat.com.br) but scope_extension=false, data_collection=false — not scoped to RoboZapp.
• dom_xss_sink crx innerHTML from variable in vendor.DzFEYc3-.js; no CSP to mitigate DOM-XSS on WhatsApp Web.
• install_url_hijack manifest onInstalled opens https://web.whatsapp.com — minor redirect, not a 3rd-party ad URL.
• content_script_sensitive_domain manifest Content script injected into https://web.whatsapp.com/* — accesses WhatsApp conversation DOM.
• js_external_hosts crx External hosts: hc-stt.hiperchat.com.br (dev-controlled), reactjs.org (CDN docs page), web.whatsapp.com.
• very_low_installs store Only 13 installs; extension is nascent and unproven — limited trust basis.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — RoboZapp [data-theft] + malext.io malicious_extension_sentry; score 4.24 -> 6.74 (+2.5 cap 2.5).
