Which versions of runtime-metrics-w7k2 are malicious?

The following npm versions of runtime-metrics-w7k2 are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate runtime-metrics-w7k2 if I installed it?

Remove runtime-metrics-w7k2 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is runtime-metrics-w7k2 part of a known attack campaign?

Yes — runtime-metrics-w7k2 is associated with the IN-MAL-2026-006899 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect runtime-metrics-w7k2 in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking runtime-metrics-w7k2 and packages like it before any post-install script runs.

What this malware does

Package declares a postinstall hook ("postinstall": "node run.js") that fires automatically on npm install. The tarball ships beacon scripts (beacon18.js, beacon_linux.js) that import child_process, os, and http, read host identifiers via os.hostname() / os.platform(), and issue outbound HTTP GET/POST requests carrying that data. The combination — automatic install-time execution, host enumeration, child_process reachability, and unsolicited outbound HTTP from an unknown low-reputation package named with a random suffix — matches a host-beacon / exfiltration shape with no legitimate library purpose. Installing this package on a developer or CI machine causes immediate disclosure of host metadata to an external endpoint and provides the publisher a foothold for follow-on commands.
