Which versions of data-utils-bcf2 are malicious?

The following npm versions of data-utils-bcf2 are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate data-utils-bcf2 if I installed it?

data-utils-bcf2 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 data-utils-bcf2 — how do I know if it already compromised me?

If data-utils-bcf2 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 data-utils-bcf2 part of a known attack campaign?

Yes — data-utils-bcf2 is associated with the IN-MAL-2026-006960 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 data-utils-bcf2 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for data-utils-bcf2 (version 1.0.0).

npm uninstall data-utils-bcf2

What this malware does

The package declares a postinstall lifecycle hook ("postinstall": "node run.js" in package.json) that automatically executes run.js on install. run.js imports os, fs, http, https, and child_process, collects host identifying information (os.hostname(), os.platform()), reads files from disk (fs.readFileSync, fs.existsSync), and issues multiple POST requests over HTTP/HTTPS (run.js lines 134, 137, 348, 355). The combination of automatic install-time execution, host fingerprinting, filesystem reads, and outbound POSTs is the canonical install-time exfiltration shape. Installing this package on a developer machine or CI runner will run the reconnaissance and exfiltration code without user interaction.
