Which versions of c8tks94kspjyhtb are malicious?

The following PyPI versions of c8tks94kspjyhtb are flagged malicious: 0.0.1, 0.0.2. Treat any of these as compromised.

How do I remediate c8tks94kspjyhtb if I installed it?

c8tks94kspjyhtb 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 c8tks94kspjyhtb — how do I know if it already compromised me?

If c8tks94kspjyhtb 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 c8tks94kspjyhtb part of a known attack campaign?

Yes — c8tks94kspjyhtb is associated with the RLMA-2025-02998, GENERIC-standard-pypi-install-pentest, RLUA-2026-00177 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
