# MAL-2026-4860: Malicious code in @qlab/ui (npm)


- **Type:** Malicious package
- **Package:** `@qlab/ui` (npm)
- **Published:** 28 May 2026

## What is MAL-2026-4860?

MAL-2026-4860 is a malicious package in @qlab/ui, published on 28 May 2026. 

### Official description

package.json declares `scripts.preinstall: node index.js`, causing index.js to run automatically during `npm install`. index.js collects `os.hostname()`, `os.userInfo().username`, `os.homedir()`, `dns.getServers()`, the current working directory, and the contents of package.json, then POSTs the payload over HTTPS to https://eo1e4fhn1i67p8r.m.pipedream.net. The same beacon is duplicated in ai/index.js, which is exposed through the package's `exports` map as `./ai`, so `require('@qlab/ui/ai')` re-fires the POST at import time. The combination of preinstall lifecycle execution, an attacker-controlled webhook endpoint, and harvesting of installer host/user/DNS/package metadata is a dependency-confusion reconnaissance beacon targeting the @qlab scope. Installers are the direct victims: simply running `npm install` ships their machine identity to the attacker.

The OpenSSF Package Analysis project identified '@qlab/ui' @ 2.0.6 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

## What should I do about MAL-2026-4860?
