Which versions of nminer are malicious?

The following npm versions of nminer are flagged malicious: 3.0.0. Treat any of these as compromised.

How do I remediate nminer if I installed it?

nminer hijacks resources to mine cryptocurrency. Remove it, check for abnormal CPU/GPU and cloud-cost spikes, and rotate any credentials exposed to the compromised process.

I already installed nminer — how do I know if it already compromised me?

If nminer 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 nminer part of a known attack campaign?

Yes — nminer is associated with the GHSA-hvrq-7pvp-2573 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 nminer across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for nminer (version 3.0.0).

What this malware does

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
