Which versions of dotevn are malicious?

The following npm versions of dotevn are flagged malicious: 17.2.1. Treat any of these as compromised.

How do I remediate dotevn if I installed it?

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

If dotevn 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 dotevn part of a known attack campaign?

Yes — dotevn is associated with the RLMA-2025-04989, RLUA-2025-05769 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 dotevn across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for dotevn (version 17.2.1).
