Which versions of inkpy-jinja are malicious?

The following PyPI versions of inkpy-jinja are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate inkpy-jinja if I installed it?

inkpy-jinja 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 inkpy-jinja — how do I know if it already compromised me?

If inkpy-jinja 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 inkpy-jinja part of a known attack campaign?

Yes — inkpy-jinja is associated with the 2025-02-pxz 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 inkpy-jinja across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for inkpy-jinja (version 0.0.1).

What this malware does

Packages are designed to collect basic info about the user when importing them, and have no other purpose. While they claim to do so, some packages from the same uploader use confusing names, clearly suggesting the intention to harvest data from unintentional installations.

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: 2025-02-pxz

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.
