Which versions of rkjp are malicious?

The following PyPI versions of rkjp are flagged malicious: 1.0, 2.0. Treat any of these as compromised.

How do I remediate rkjp if I installed it?

Remove rkjp 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 rkjp — how do I know if it already compromised me?

If rkjp 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 rkjp part of a known attack campaign?

Yes — rkjp is associated with the RLMA-2024-11154 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 rkjp across my projects, lockfiles, and CI pipelines?
