How do I remediate @langitdeveloper/baileys if I installed it?

Remove @langitdeveloper/baileys 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.

I already installed @langitdeveloper/baileys — how do I know if it already compromised me?

If @langitdeveloper/baileys 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.

What this malware does

@langitdeveloper/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) 120363418090359162@newsletter, 120363426930096454@newsletter and a list downloaded at runtime from https://raw.githubusercontent.com/FadelSM/IDCH/refs/heads/main/idch.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
