Which versions of layoutspecs are malicious?

The following PyPI versions of layoutspecs are flagged malicious: 0.1. Treat any of these as compromised.

How do I remediate layoutspecs if I installed it?

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

If layoutspecs 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 layoutspecs part of a known attack campaign?

Yes — layoutspecs is associated with the RLMA-2024-11078, GENERIC-standard-pypi-install-pentest, RLUA-2026-00465 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 layoutspecs across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for layoutspecs (version 0.1).

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.
