Which versions of selib are malicious?

The following PyPI versions of selib are flagged malicious: 3.0.1. Treat any of these as compromised.

How do I remediate selib if I installed it?

Remove selib from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed selib — how do I know if it already compromised me?

If selib 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 selib part of a known attack campaign?

Yes — selib is associated with the RLMA-2024-04784, RLUA-2024-09248 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 selib across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for selib (version 3.0.1).

Detect & block this

O3 blocks selib-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
