🟡 MEDIUM RISK — review
Top Risks
- Uninstall URL hijack active: extension redirects on uninstall to track/monetize uninstalls.
- Privacy policy is Google's own policy — not scoped to this extension; admits data collection and 3rd-party sharing.
- WhatsApp brand impersonation: dev does not own WhatsApp; confirmed_owner=false.
- Content script on WhatsApp Web can read all chat messages; 10 external wascript.com.br endpoints contacted.
- function_constructor (new Function) + innerHTML DOM-XSS sink in injected scripts with no CSP.
Evidence
- uninstall_url_hijack manifest chrome.runtime.setUninstallURL() set; uninstall_url_target=null but hijack confirmed true.
- install_url_hijack manifest onInstalled opens https://web.whatsapp.com — 3rd-party redirect on install.
- brand_impersonation store brand_mention.is_impersonation=true for WhatsApp; developer domain extensao.store is not Meta/WhatsApp.
- generic_privacy_policy store Privacy URL is Google Account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
- external_hosts_volume crx 10 distinct wascript.com.br subdomains plus generativelanguage.googleapis.com and mail.google.com contacted.
- code_quality_function_constructor crx new Function() constructor found in injected content script — arbitrary code execution risk.
- no_csp manifest content_security_policy is null; MV3 default applies but csp_present=false increases DOM-sink risk.
- reputation_no_verified_publisher store Developer 'wspd' email at extensao.store; not verified, not featured, no recognised org.
Permissions Breakdown
- unlimitedStorage low Allows unlimited local storage; low direct harm but enables large data caching.
- storage low Standard local key-value storage; low risk in isolation.
- alarms low Scheduled tasks; minimal risk on its own.
