## What is MAL-2026-15825?

MAL-2026-15825 is a malicious package in real-router-utils, published on 2 Sep 2026. 

### Official description

package.json declares a preinstall script that runs an inline node command reading the installer's OS hostname, username, and current working directory and sending them as query parameters to a hardcoded webhook.site collector URL (https://webhook.site/e32d3b8a-a5df-40cc-ae60-7a8343b581e4). The request fires automatically on npm install, before any user interaction, and the destination is an anonymous ephemeral webhook endpoint unrelated to any documented package purpose.

## What should I do about MAL-2026-15825?

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