OpenSSF/OSV malware advisory MAL-2026-18676 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as clean; the assessments disagree.

Independent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree.

OpenSSF/OSV advisory MAL-2026-18676 confirms this npm version as malicious. @dyllxnn/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) 120363408893555851@newsletter, 120363412076734264@newsletter (stored base64-encoded), using the victim's authenticated session...

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified.

- **Trigger:** Installation runs a Node.js version check; importing the entry point prints attribution; WhatsApp network operations occur through the client API.

- **Impact:** No automatic credential theft, unrelated account action, or other attack behavior was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-05T07:12:31.052Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The install hook checks the runtime version, GraphQL requests use WhatsApp endpoints, and fixed newsletter metadata is used while building a message for the caller-provided destination.

- **Rationale:** The install hook only enforces a Node.js version requirement. The flagged GraphQL requests target WhatsApp hosts, and the fixed newsletter identifier is embedded in message metadata only when the caller invokes sendMessage for a chosen recipient.

- **Network endpoints:** graph.whatsapp.com, acs.whatsapp.com, wamo.whatsapp.net

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The preinstall script only checks the Node.js major version and exits on versions below 20., The package entry point exports the WhatsApp client and prints developer and package attribution at import time., GraphQL credentials are sent to the WhatsApp endpoint configured by the package., The fixed newsletter identifier appears in metadata for a message sent to the caller-provided JID., The special message handling is reached through the explicit sendMessage method.

- **Evidence against:** The package includes a custom media utility that invokes ffmpeg through child\_process.exec., Importing the package prints promotional attribution, including the developer's channel.

## Affected versions and remediation

This report applies to @dyllxnn/baileys@1.0.0.

- Avoid installing @dyllxnn/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.
