What is MAL-2026-16361?

MAL-2026-16361 is a malicious package in @uh-platform/nadaver2, published on 21 Sep 2026.

Official description

The package's package.json declares a preinstall lifecycle hook that runs node index.js. index.js invokes child_process.exec on a curl command whose URL embeds $(hostname) and $(whoami) as DNS subdomains of nadaver.pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com, a Burp Collaborator (OAST) endpoint. On npm install, the installer's hostname and OS username are transmitted to that attacker-controlled collaborator host via DNS and HTTP. The @uh-platform scope and the name shape are consistent with a dependency-confusion probe. There is no legitimate SDK, build, or install functionality in the package.

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.

What should I do about MAL-2026-16361?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
