Which versions of cloudpedia are malicious?

The following npm versions of cloudpedia are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate cloudpedia if I installed it?

Remove cloudpedia 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 cloudpedia — how do I know if it already compromised me?

If cloudpedia 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.

How do I find cloudpedia across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for cloudpedia (version 1.0.0).

What this malware does

cloudpedia 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 a list downloaded at runtime from https://raw.githubusercontent.com/Xcloudpedia/Screaper/refs/heads/main/idChannel.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
