# MAL-2026-15897: Malicious code in easypanel-core (npm)


- **Type:** Malicious package
- **Package:** `easypanel-core` (npm)
- **Published:** 4 Sep 2026

## What is MAL-2026-15897?

MAL-2026-15897 is a malicious package in easypanel-core, published on 4 Sep 2026. 

### Official description

easypanel-core ships an inert `module.exports = {}` main and places all functionality in a preinstall lifecycle script. On `npm install`, preinstall.js collects os.hostname(), os.userInfo().username, process.cwd(), and the names of CI-related environment variables, base64url-encodes them, and transmits the data to `*.daco3v4q6f49egu1ds1gwjnsjb88s5kcp.oob.lyomeri.com` via both a DNS subdomain lookup and an HTTP GET to `/npm/<encoded>`. The package name mimics the easypanel project and the description advertises a 'client library', while the shipped library exports nothing and provides no functionality — the install-time beacon is the sole behavior.

## What should I do about MAL-2026-15897?

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