Which versions of ts-migrate-example are malicious?

The following npm versions of ts-migrate-example are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate ts-migrate-example if I installed it?

ts-migrate-example is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed ts-migrate-example — how do I know if it already compromised me?

If ts-migrate-example 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 ts-migrate-example part of a known attack campaign?

Yes — ts-migrate-example is associated with the GHSA-f843-8w79-2v4m, RLMA-2025-05971 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 ts-migrate-example across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for ts-migrate-example (version 99.0.0).

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall ts-migrate-example

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.

This package installs a dependency hosted on a custom domain that runs an info stealer during installation. The info stealer focuses on stealing npm, git, and other CI/CD related tokens.
