Which versions of robase-install are malicious?

The following PyPI versions of robase-install are flagged malicious: 2.1.0. Treat any of these as compromised.

How do I remediate robase-install if I installed it?

robase-install 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 robase-install — how do I know if it already compromised me?

If robase-install 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 robase-install part of a known attack campaign?

Yes — robase-install is associated with the 2026-03-roboat-addition 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 robase-install across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for robase-install (version 2.1.0).
