Which versions of amazon-core are malicious?

The following npm versions of amazon-core are flagged malicious: 99.1.1. Treat any of these as compromised.

How do I remediate amazon-core if I installed it?

Remove amazon-core 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 amazon-core — how do I know if it already compromised me?

If amazon-core 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 amazon-core part of a known attack campaign?

Yes — amazon-core is associated with the RLMA-2026-04829, RLUA-2026-05965 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 amazon-core across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for amazon-core (version 99.1.1).
