Which versions of partner-tracker are malicious?

The following npm versions of partner-tracker are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate partner-tracker if I installed it?

Remove partner-tracker from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed partner-tracker — how do I know if it already compromised me?

If partner-tracker 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 partner-tracker part of a known attack campaign?

Yes — partner-tracker is associated with the GHSA-49v3-3255-4m4h 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 partner-tracker across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for partner-tracker (version 99.0.0).
