Which versions of metrics-probe-dc85 are malicious?

The following npm versions of metrics-probe-dc85 are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate metrics-probe-dc85 if I installed it?

metrics-probe-dc85 is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed metrics-probe-dc85 — how do I know if it already compromised me?

If metrics-probe-dc85 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 metrics-probe-dc85 part of a known attack campaign?

Yes — metrics-probe-dc85 is associated with the IN-MAL-2026-006901, GHSA-49m3-wjc7-7pxw 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 metrics-probe-dc85 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for metrics-probe-dc85 (version 1.0.0).

What this malware does

On install, package.json declares postinstall: node run.js, which auto-executes run.js when the package is installed. run.js imports os, fs, http, https, and child_process, collects host identity via os.hostname() and os.platform(), reads from the local filesystem, and POSTs the gathered data over HTTP/HTTPS. The combination of automatic install-time execution, host-identity enumeration, filesystem reads, and outbound POST traffic is the canonical install-time host-fingerprinting / exfiltration pattern. Installing this package causes the installer's machine identity and local file content to be sent to a remote endpoint without consent.

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.
