Which versions of pylibcugraph are malicious?

The following PyPI versions of pylibcugraph are flagged malicious: 0.0.0, 0.0.1. Treat any of these as compromised.

How do I remediate pylibcugraph if I installed it?

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

If pylibcugraph 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 pylibcugraph part of a known attack campaign?

Yes — pylibcugraph is associated with the GENERIC-standard-pypi-install-pentest, RLMA-2025-06582, RLUA-2026-00639 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 pylibcugraph across my projects, lockfiles, and CI pipelines?

Advisory published Nov 13, 2025Updated Mar 19, 2026

pylibcugraph is a confirmed malicious PyPI package (MAL-2025-191835) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.0, 0.0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in pylibcugraph (PyPI)

MAL-2025-191835

Immediate action

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

pip uninstall pylibcugraph

What this malware does

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: GENERIC-standard-pypi-install-pentest

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.
