Which versions of pytiob are malicious?

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

How do I remediate pytiob if I installed it?

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

If pytiob 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 pytiob part of a known attack campaign?

Yes — pytiob is associated with the RLMA-2024-09072, funcaptcha-ru 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 pytiob across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for pytiob (version 1.0.0).
