Top Risks

• Uninstall URL hijack detected — extension registers custom uninstall URL, a monetization/tracking red flag.
• Install URL hijack: onInstalled redirects user to whatsapp web — suspicious onboarding flow.
• Privacy policy is Google's generic policy (not scoped to this extension) but ADMITS data collection and 3rd-party sharing → +10 privacy score.
• 10 distinct external wascript.com.br/watools.com.br endpoints contacted — broad backend surface on WhatsApp message content.
• new Function() constructor found in scanned JS — dynamic code execution risk without CSP protection.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL() called; target null but hijack flag true — +3.0 webstore.
• install_url_hijack crx onInstalled opens https://web.whatsapp.com — +2.0 webstore install hijack.
• generic_privacy_policy store Policy 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 hosts — broad backend network surface on WhatsApp content.
• function_constructor crx new Function() constructor found in JS — dynamic code execution, +2.5 code quality.
• dom_sink_innerhtml_userctrl crx innerHTML from variable, no CSP present → elevated to +2.0 code quality (FIX B).
• no_csp manifest csp_present=false on MV3; does not add MV2 penalty but amplifies code findings.
• reputation_signals store Not verified publisher, not featured, dev name 'wspd' sparse, domain extensao.store resolves but low trust.

Permissions Breakdown

• unlimitedStorage low Allows unbounded local storage; low risk in isolation.
• storage low Standard local key-value storage, low sensitivity.
• alarms low Scheduling; can be used for persistence but low direct harm.
• tabs medium Access to tab URLs/titles; medium risk when paired with host access.
• https://web.whatsapp.com/* medium Scoped host permission; allows full content access on WhatsApp Web including messages.
