Which versions of presudo-generate are malicious?

The following PyPI versions of presudo-generate are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate presudo-generate if I installed it?

presudo-generate 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 presudo-generate — how do I know if it already compromised me?

If presudo-generate 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 presudo-generate part of a known attack campaign?

Yes — presudo-generate is associated with the RLMA-2025-00492, 2024-12-langer-updater, RLUA-2026-00604 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 presudo-generate across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for presudo-generate (version 1.0.0).

Part of a larger attack: 2024-12-langer-updater published 9 malicious packages. See the full campaign →

presudo-generatePyPI

Advisory published Dec 16, 2024Updated Mar 19, 2026

MAL-2025-951

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall presudo-generate

What this malware does

During installation, the package collects quite extensive information about the host and has no other purpose. To avoid detection, the real code is put in a ZIP archive and includes also some VM-detection techniques. The malicious code is activated via metaclass set for the "install" command class in setup.py

Over the time, techniques used in packages are slightly changing, including that some of marked packages don't have malicious part, but rather are used only for tests.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2024-12-langer-updater

Reasons (based on the campaign):

The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
The package overrides the install command in setup.py to execute malicious code during installation.
exfiltration-env-variables
The package contains code to detect if it is running in a sandbox environment.

Detect & block this

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