Top Risks

• Privacy policy is Google's own policy — not scoped to this extension; collects+shares data with no extension-specific disclosure.
• Uninstall URL hijack flagged: extension registers an uninstall redirect to 3rd party.
• Install URL hijack opens web.whatsapp.com on install — onInstalled redirect pattern.
• 10+ external wascript.com.br/watools.com.br endpoints contacted; broad backend surface for a 7-install CRM tool.
• Brand impersonation: Google brand mentioned in privacy policy URL, developer not a confirmed Google affiliate.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL() registered — classic monetization/tracking pattern (target null but flag set).
• install_url_hijack crx onInstalled opens https://web.whatsapp.com — low-severity but confirms redirect pattern.
• privacy_policy_generic store Policy URL is Google's own privacy page; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• js_external_hosts crx 10 distinct wascript.com.br / watools.com.br subdomains in external host list; no CSP to constrain them.
• brand_impersonation store brand_mention.is_impersonation=true (Google), confirmed_owner=false, not verified publisher.
• function_constructor crx new Function() constructor found in bundled JS — code_quality +2.5.
• dom_sink_innerhtml_userctrl crx innerHTML from variable with no CSP present → elevated DOM-XSS risk (+2.0 code quality).
• no_csp manifest csp_present=false on MV3; no content_security_policy declared — amplifies code findings.

Permissions Breakdown

• unlimitedStorage low Allows unbounded local storage; low direct harm but enables large local data accumulation.
• storage low Standard key-value storage; low risk in isolation.
• alarms low Scheduling API; low risk, enables background polling.
• tabs medium Can read tab URLs and titles; moderate privacy risk scoped to WhatsApp use.
• https://web.whatsapp.com/* medium Host permission on WhatsApp Web; allows reading/injecting into chat sessions.
