# MAL-2026-12386: Malicious code in fundraiserservpp (npm)

## What is MAL-2026-12386?

MAL-2026-12386 is a malicious package in fundraiserservpp, published on 5 Aug 2026. 

### Official description

fundraiserservpp@2.0.0 runs `node index.js` as a `preinstall` lifecycle script on `npm install`. The script collects host metadata from the installer machine — `os.hostname()`, `os.platform()`, `os.arch()`, the user home directory path, and configured DNS servers — and issues an HTTPS POST to a hardcoded Burp Collaborator subdomain (`mrh99ucv1u3kyeba1020ae2t7kdc12pr.oastify.com/hit`) with that data as a JSON body. The beacon fires automatically at install time with no user interaction. The destination is an attacker-controlled out-of-band interaction endpoint typical of dependency-confusion reconnaissance, confirming to the operator that the package name was successfully resolved and installed inside a target build environment.

## What should I do about MAL-2026-12386?

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