Which versions of platform-telemetry-client are malicious?

The following PyPI versions of platform-telemetry-client are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate platform-telemetry-client if I installed it?

platform-telemetry-client 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 platform-telemetry-client — how do I know if it already compromised me?

If platform-telemetry-client 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 platform-telemetry-client part of a known attack campaign?

Yes — platform-telemetry-client is associated with the 2026-09-platform-telemetry-client 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 platform-telemetry-client across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for platform-telemetry-client (version 1.0.0).
