What this malware does

[email protected] ships an empty stub (index.js: module.exports = {};) with no description, author, or repository, but declares a single dependency ltidisafe as a direct tarball URL: https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.0.6.tgz. The bucket is on Google Cloud Storage, unrelated to any documented publisher, and the bucket/path naming (ltidi/depenconf) is consistent with a dependency-confusion staging area. URL-tarball dependencies bypass the npm registry's visibility, signature, and tooling — npm install will fetch the.tgz directly and execute any preinstall/install/postinstall lifecycle scripts it ships, with no hash pin, no signature, and no registry review. The wrapper contributes no functionality; its only effect on install is to smuggle the off-registry tarball into the installer's dependency tree. The high version number (99.9.1) and absent metadata are also consistent with a dependency-confusion lure intended to outrank an internal package of the same name.

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.

The OpenSSF Package Analysis project identified 'firefly-utilities-helper' @ 99.9.1 (npm) as malicious.

It is considered malicious because:

  • The package communicates with a domain associated with malicious activity.

Detection & response playbook

Malicious package
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for firefly-utilities-helper (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging firefly-utilities-helper across your stack and pipelines.

  2. If you installed it — respond

    Remove firefly-utilities-helper 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.

  3. Did it already run?

    If firefly-utilities-helper was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks firefly-utilities-helper before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. firefly-utilities-helper on npm has been identified as a malicious package (versions 99.9.0, 99.9.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
