Which versions of pui-diagnostics are malicious?

Every published version of pui-diagnostics on npm is considered malicious. Remove the package entirely.

How do I remediate pui-diagnostics if I installed it?

Remove pui-diagnostics 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is pui-diagnostics part of a known attack campaign?

Yes — pui-diagnostics is associated with the GHSA-96f9-39p2-gjwm campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect pui-diagnostics in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking pui-diagnostics and packages like it before any post-install script runs.

What this malware does

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
