Which versions of vinzz-wcli are malicious?

The following npm versions of vinzz-wcli are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate vinzz-wcli if I installed it?

Remove vinzz-wcli 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 vinzz-wcli — how do I know if it already compromised me?

If vinzz-wcli 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.

Yes — vinzz-wcli is associated with the IN-MAL-2026-019724 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 vinzz-wcli across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for vinzz-wcli (version 1.0.1).

What this malware does

vinzz-wcli is a WhatsApp CLI whose main entry (index.js) sets global.ownerr = "[email protected]" and treats any incoming WhatsApp message from that JID as coming from an authorized owner. The messages.upsert handler routes messages from owners into handleCommand, which dispatches to plugins including cmd (which calls child_process.exec on the message text) and eval (which builds and runs an AsyncFunction from the message text). When an installer runs the CLI and pairs their own WhatsApp account, the hardcoded third-party number is silently added as an owner and can send arbitrary shell commands and JavaScript to be executed on the installer's host with the installer's privileges. The tarball also ships a second file, index2.js, which is not the declared main but contains the same hardcoded owner JID and the same messages.upsert -> handleCommand dispatch, providing an equivalent execution path if that file is invoked directly.
