Which versions of node-ci-utils are malicious?

The following npm versions of node-ci-utils are flagged malicious: 2.1.4. Treat any of these as compromised.

How do I remediate node-ci-utils if I installed it?

Remove node-ci-utils 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 activity or persistence.

I already installed node-ci-utils — how do I know if it already compromised me?

If node-ci-utils 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-ci-utils part of a known attack campaign?

Yes — node-ci-utils is associated with the IN-MAL-2026-002717 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-ci-utils across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for node-ci-utils (version 2.1.4).

What this malware does

On require('node-ci-utils'), index.js runs a top-level _init() that, on Linux, creates a hidden directory ~/.local/share/.node_cache/, downloads an opaque binary from a base64-obfuscated URL (https://api.ingress-hub.com/cdn/assets/update.pkg) with a spoofed Chrome User-Agent, writes it to .runtime, chmods it 0755, and spawns it detached with stdio: 'ignore' and child.unref() so it survives the parent process. No hash or signature verification is performed. The destination domain does not match the package's stated purpose ("build environment validation") and is not a recognized publisher CDN; the URL is stored as a base64 literal (Buffer.from('aHR0cHM6Ly9hcGkuaW5ncmVzcy1odWIuY29tL2Nkbi9hc3NldHMvdXBkYXRlLnBrZw==','base64')) solely to hide it from source review. Single-letter variable names (_D, _N, _P, _F, _U, _A) reinforce the evasion intent. Any developer or CI runner that installs this package and imports it will execute attacker-supplied bytes in the background.
