## What is MAL-2026-14139?

MAL-2026-14139 is a malicious package in prism-registry, published on 18 Aug 2026. 

### Official description

The package declares `preinstall: "node index.js"`, which fires automatically on `npm install`. index.js collects host identifiers (os.hostname, os.userInfo, home directory, DNS servers, __dirname, package.json contents) and reads the local files /etc/passwd and /etc/hosts, then POSTs the aggregated JSON over HTTPS to the hardcoded Burp Collaborator subdomain zjmjb1b5mnwtdcmzrsq6uj4bj2ptdj18.oastify.com. There is no legitimate functionality in the package beyond this beacon.

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-2026-14139?

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