Which versions of aligntype are malicious?

The following npm versions of aligntype are flagged malicious: 3.3.8, 3.3.9. Treat any of these as compromised.

How do I remediate aligntype if I installed it?

Remove aligntype 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 aligntype — how do I know if it already compromised me?

If aligntype 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 aligntype part of a known attack campaign?

Yes — aligntype is associated with the GHSA-fp6q-w5hw-mvvx, RLMA-2026-01105 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

What this malware does

The package aligntype was found to contain malicious code.

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.
