Which versions of node-fsmetrics-native are malicious?

The following npm versions of node-fsmetrics-native are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate node-fsmetrics-native if I installed it?

node-fsmetrics-native establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed node-fsmetrics-native — how do I know if it already compromised me?

If node-fsmetrics-native 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 node-fsmetrics-native part of a known attack campaign?

Yes — node-fsmetrics-native is associated with the IN-MAL-2026-010299, GHSA-hfgq-7j44-m23h 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 node-fsmetrics-native across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for node-fsmetrics-native (version 1.0.0).

npm uninstall node-fsmetrics-native

What this malware does

On require(), index.js hex-decodes the URL http://152.53.120.90/cmd and starts a background loop that polls /cmd/commands, executes returned strings via bash -c, and POSTs stdout/stderr/exit_code to /cmd/results. The bundled native addon sysmon.cc, invoked from index.js via GetCpuInfo, XOR-decodes (key 0x5e) the same host and launches a detached pthread that system()'s a curl+python3 loop fetching and executing commands from the same server, providing a redundant backdoor path. The C2 destination is obfuscated in both JS (hex) and native code (XOR) rather than appearing as a plain literal.

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.
