Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Normal creation of a WhatsApp socket activates an aggressive anti-ban wrapper by default. It modifies outbound-message timing and rejects messages according to account-risk tracking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-30T10:29:07.235Z - **Finished:** 2026-09-30T10:30:18.483Z - **Download time:** 762 ms - **Static scan time:** 5675 ms - **AI review time:** 64810 ms - **Total time:** 71248 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Normal creation of a WhatsApp socket activates an aggressive anti-ban wrapper by default. It modifies outbound-message timing and rejects messages according to account-risk tracking. - **Trigger:** Import the library and call its default socket constructor without setting antiban to false. - **Impact:** It can facilitate automated WhatsApp messaging while attempting to reduce platform enforcement. - **Evidence paths:** lib/Socket/index.js, lib/antiban.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T10:30:18.483Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default outbound-message interception for enforcement evasion. - **Rationale:** The package contains a default-on anti-ban mechanism that materially enables evasion of WhatsApp controls. Its lifecycle hook is benign and no concrete malware chain was found, so this is a dangerous capability rather than confirmed malware. - **Files touched:** lib/Socket/index.js, lib/antiban.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for block:** The default socket constructor automatically enables an aggressive anti-ban layer unless callers explicitly opt out., The wrapper intercepts every send, delays it, and blocks messages based on anti-ban decisions., The anti-ban presets deliberately throttle and warm up accounts, creating a WhatsApp-enforcement-evasion capability. - **Evidence against:** The preinstall hook only checks the Node.js major version and does not modify files or contact a network service., Webhook delivery is configured by the caller; no fixed package-owned exfiltration endpoint was found., No credential harvesting, remote payload loading, or destructive install-time behavior was found in the inspected files. ## Affected versions and remediation This report applies to @wanzlonely/bails4u@3.0.0. - Avoid installing @wanzlonely/bails4u@3.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
