Which versions of alchemyrpcs are malicious?

The following PyPI versions of alchemyrpcs are flagged malicious: 1.1.7, 1.1.8. Treat any of these as compromised.

How do I remediate alchemyrpcs if I installed it?

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

If alchemyrpcs 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 alchemyrpcs part of a known attack campaign?

Yes — alchemyrpcs is associated with the RLMA-2025-02555, 2025-04-alchemyrpcs, RLUA-2026-00053 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
