Which versions of rsa2026 are malicious?

The following PyPI versions of rsa2026 are flagged malicious: 213.9. Treat any of these as compromised.

How do I remediate rsa2026 if I installed it?

Remove rsa2026 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 rsa2026 — how do I know if it already compromised me?

If rsa2026 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 rsa2026 part of a known attack campaign?

Yes — rsa2026 is associated with the RLMA-2025-05636 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 rsa2026 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for rsa2026 (version 213.9).
