Which versions of nfd are malicious?

The following PyPI versions of nfd are flagged malicious: 1.0. Treat any of these as compromised.

How do I remediate nfd if I installed it?

nfd 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 nfd — how do I know if it already compromised me?

If nfd 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 nfd part of a known attack campaign?

Yes — nfd is associated with the 2026-03-old-nai 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 nfd across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for nfd (version 1.0).

What this malware does

Facebook automation/hacking tool, with a part of its code obfuscated. Given that other packages from this uploader exfiltrate user's credentials, this is likely to hide a malicious action.

Detect & block this

O3 blocks nfd-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
