Which versions of ntoutils are malicious?

The following PyPI versions of ntoutils are flagged malicious: 1.3.1, 1.3.2. Treat any of these as compromised.

How do I remediate ntoutils if I installed it?

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

If ntoutils 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 ntoutils part of a known attack campaign?

Yes — ntoutils is associated with the 2026-02-ntoutils 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 ntoutils across my projects, lockfiles, and CI pipelines?

Detect & block this

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