Which versions of xzvbailsx are malicious?

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

How do I remediate xzvbailsx if I installed it?

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

If xzvbailsx 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.

Is xzvbailsx part of a known attack campaign?

Yes — xzvbailsx is associated with the IN-MAL-2026-020177 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

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

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

What this malware does

package.json declares the dependency libsignal with source github:tenka-san/libsignal-node, an unpinned GitHub ref with no commit SHA, tag, or integrity hash. On npm install, npm fetches whatever HEAD of that repository currently points at and executes any lifecycle scripts (preinstall/install/postinstall) it contains on the installer's machine. The referenced GitHub account is a personal repository unrelated to the WhiskeySockets/Baileys upstream that this package forks. Provenance is further obscured by an identity mismatch: the package is published as xzvbailsx but README/examples describe it as @XzV-RxVz/xbails, and the repository field points to Telegram handles (t.me/JustRxVz, t.me/XzV_ExpzC) rather than a source repository.
