Which versions of colorina are malicious?

The following PyPI versions of colorina are flagged malicious: 0.1.0, 0.1.2, 0.1.3, 0.1.4, 0.1.5, 0.1.6, 0.2.0, 0.2.2, 0.2.3, 0.2.4, 0.2.5. Treat any of these as compromised.

How do I remediate colorina if I installed it?

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

If colorina 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 colorina part of a known attack campaign?

Yes — colorina is associated with the RLMA-2025-02502, 2025-04-colorina, RLUA-2026-00213, RLUA-2026-02067 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
