Which versions of aligntyper are malicious?

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

How do I remediate aligntyper if I installed it?

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

If aligntyper 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 aligntyper part of a known attack campaign?

Yes — aligntyper is associated with the RLMA-2026-01107 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 aligntyper across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for aligntyper (version 3.3.9).
