Is @finzzcloud/baileys safe?

Version 1.0.0 of @finzzcloud/baileys was compromised (covert WhatsApp channel hijack (PhantomSub)). Other versions are not flagged as malicious. npm's latest tag points to 1.0.0, one of these versions, so an unpinned install gets it.

Do not install @finzzcloud/baileys 1.0.0

Covert WhatsApp channel hijack (PhantomSub). Added to CyberXYZ 2026-11-07, verified by a CyberXYZ analyst.

// what we observed

Covert WhatsApp channel hijack (PhantomSub). After the library connects a WhatsApp session, the listed versions make the account follow WhatsApp channels the publisher chose, without the user asking and without telling them. CyberXYZ read every version published by 2026-11-06 from the npm registry (a static read, nothing executed); the listed versions are the ones that do this.

// versions and what to do

Malicious: 1.0.0
Move to: Pin a release that is not listed above: the latest tag points to one that is.

If one of these versions was installed, remove it and treat the credentials, tokens and SSH keys on that machine as exposed: rotate them. Check CI runners and container images that installed it too.
