What this malware does

wileys-neji 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) 120363303656790201@newsletter, 120363404743164316@newsletter (stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for wileys-neji (version 2.0.3).

  2. If you installed it — respond

    Remove wileys-neji from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If wileys-neji was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
