Which versions of byted-torch-monitor are malicious?

The following PyPI versions of byted-torch-monitor are flagged malicious: 0.0.1, 0.2. Treat any of these as compromised.

How do I remediate byted-torch-monitor if I installed it?

byted-torch-monitor 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 byted-torch-monitor — how do I know if it already compromised me?

If byted-torch-monitor 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 byted-torch-monitor part of a known attack campaign?

Yes — byted-torch-monitor is associated with the RLMA-2025-02558, 2025-04-byted-torch-monitor, RLUA-2026-00169 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
