# MAL-2026-11131: Malicious code in basic-vite (npm)


- **Type:** Malicious package
- **Package:** `basic-vite` (npm)
- **Published:** 28 Jul 2026

## What is MAL-2026-11131?

MAL-2026-11131 is a malicious package in basic-vite, published on 28 Jul 2026. 

### Official description

package.json declares `preinstall: node index.js`, so `npm install basic-vite` auto-executes index.js. The script collects host identity data (hostname, username, home directory, DNS servers, current working directory, package.json contents) and reads /etc/passwd and /etc/hosts, then POSTs the collected payload over HTTPS to the hardcoded Burp Collaborator subdomain md3wko7hlcmvfsq16xh2higublhc53ts.oastify.com. The package name suggests a Vite-related utility, but no such functionality is present; the sole behavior is install-time data exfiltration to an attacker-controlled out-of-band interaction host.

## What should I do about MAL-2026-11131?

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