# MAL-2026-13444: Malicious code in dpdgroup-css (npm)


- **Type:** Malicious package
- **Package:** `dpdgroup-css` (npm)
- **Published:** 6 Aug 2026

## What is MAL-2026-13444?

MAL-2026-13444 is a malicious package in dpdgroup-css, published on 6 Aug 2026. 

### Official description

package.json declares both preinstall and postinstall lifecycle hooks that run `node setup.js` on every `npm install`. setup.js reads the installer's machine hostname via `os.hostname()` and issues an HTTP GET to a hardcoded bare-IP callback at http://89.116.25.133:4444/dpdgroup-css/<hostname>, with the hostname also carried in an `X-PoC-Host` header. The package name `dpdgroup-css` resembles an internal scope for the DPDgroup courier organization, consistent with a dependency-confusion attack: a private build that resolves this public version instead of an intended internal package auto-runs the beacon and discloses the internal build-host identifier to an external, non-first-party bare-IP endpoint. No legitimate library functionality is present.

## What should I do about MAL-2026-13444?

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