LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-18679 confirms this npm version as malicious. @monze1239/baileys is a fork of the Baileys WhatsApp Web library that silently subscribes the installer's own WhatsApp account to WhatsApp Channels chosen by the publisher. When the socket connects, code in lib/Socket/newsletter.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363413848171447@newsletter (stored base64-encoded), using the victim's authenticated session and without telling them... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-11-05T07:10:20.408Z - **Finished:** 2026-11-05T07:11:28.182Z - **Download time:** 1535 ms - **Static scan time:** 1732 ms - **AI review time:** 64505 ms - **Total time:** 67774 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:** Automatically alters some outgoing WhatsApp messages with fabricated forwarding and newsletter metadata. - **Trigger:** A caller uses \`sendMessage\` with album content, or invokes the event or poll-result handlers. - **Impact:** Recipients may be misled about a message’s origin or association. The inspected code does not establish an automatic follow, post to a channel, or credential transfer. - **Evidence paths:** lib/Socket/messages-send.js, lib/Socket/luxu.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T07:11:28.182Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handlers add hard-coded newsletter identifiers and false forwarding/context fields before relaying messages. - **Rationale:** The install hook is only a Node version check, and the inspected GraphQL transport uses WhatsApp endpoints. However, message handlers automatically add fabricated forwarding/newsletter metadata to outgoing messages, creating a user-visible deception risk; the evidence does not establish a direct account action against the embedded channel targets. - **Files touched:** lib/Socket/luxu.js - **Network endpoints:** graph.whatsapp.com, acs.whatsapp.com, wamo.whatsapp.net ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** The \`preinstall\` script only checks the Node.js major version and exits on versions below 20., When \`sendMessage\` receives an album, it automatically routes it through \`handleAlbum\`., \`handleAlbum\` adds fabricated forwarded-newsletter and message-context metadata to each album item before relaying it., Other message handlers also embed hard-coded newsletter identifiers in outgoing message metadata. - **Evidence against:** GraphQL requests target WhatsApp hosts and use a token acquired through the socket’s nonce exchange., The main entry point’s visible import-time behavior prints package branding; it does not show an automatic account action. ## Affected versions and remediation This report applies to @monze1239/baileys@1.0.0. - Avoid installing @monze1239/baileys@1.0.0. 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.
