Which versions of evil-rce are malicious?

The following PyPI versions of evil-rce are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate evil-rce if I installed it?

evil-rce 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 evil-rce — how do I know if it already compromised me?

If evil-rce 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 evil-rce part of a known attack campaign?

Yes — evil-rce is associated with the 2025-12-evil-rce 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 evil-rce across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for evil-rce (version 1.0.0).
