Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Creating the normal WhatsApp socket silently follows a package-selected WhatsApp channel by default. The channel target is concealed as Base64 and the action is delayed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-14T02:37:59.279Z - **Finished:** 2026-09-14T02:38:54.761Z - **Download time:** 506 ms - **Static scan time:** 1503 ms - **AI review time:** 53472 ms - **Total time:** 55482 ms The recorded confidence comes from the underlying analysis.

The channel target is concealed as Base64 and the action is delayed. - **Trigger:** A consumer calls makeWASocket without explicitly disabling autoFollow. - **Impact:** The package changes the user's WhatsApp newsletter subscriptions without informed consent; its checkBan helper also discloses supplied phone numbers to an unrelated host. - **Evidence paths:** lib/Defaults/index.js, lib/Socket/newsletter.js, lib/Socket/index.js, lib/Socket/socket.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T02:38:54.761Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default-enabled delayed account-follow request to a concealed channel. - **Attack narrative:** The package merges defaults into every makeWASocket call. Those defaults enable autoFollow, and the socket layer decodes a concealed WhatsApp channel URL before issuing a delayed FOLLOW request. This is an unrequested account-state change embedded in routine client initialization. Separately, the exported checkBan helper transmits a caller-provided phone number to an unrelated domain. - **Rationale:** This package contains a concealed, default-on action that changes a user's WhatsApp subscriptions during ordinary socket creation. The unrelated phone-number lookup endpoint reinforces that the fork adds non-package-aligned network behavior. - **Network endpoints:** wss://web.whatsapp.com/ws/chat, https://xzc-corporation.biz.id/lrp?number= ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The default configuration enables automatic following., Socket construction decodes an obscured channel URL and follows it after a delay., The automatic follow is reached by the normal makeWASocket construction path., A separate exported function sends supplied phone numbers to an unrelated third-party host. - **Evidence against:** The preinstall hook only rejects Node.js versions below 20., The media file and protocol constants match the package's WhatsApp client functionality; no install-time payload download or credential harvesting was found. ## Affected versions and remediation This report applies to xzbails@0.0.4. - Avoid installing xzbails@0.0.4. 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.
