Which versions of lazy-attr are malicious?

Every published version of lazy-attr on npm is considered malicious. Remove the package entirely.

How do I remediate lazy-attr if I installed it?

Remove lazy-attr 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 lazy-attr — how do I know if it already compromised me?

If lazy-attr 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 lazy-attr part of a known attack campaign?

Yes — lazy-attr is associated with the GHSA-pm6r-2g8f-89qh 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 lazy-attr across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for lazy-attr (all published versions).

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.
