## What is MAL-2026-10205?

MAL-2026-10205 is a malicious package in library-explorer, published on 12 Jul 2026. 

### Official description

package.json declares `preinstall: node index.js`. On `npm install`, index.js collects installer host identity (os.hostname, os.platform, os.arch, os.homedir, os.userInfo username/uid/gid/shell, CPU/memory) and shells out `whoami` and (non-Windows) `id` via child_process.exec, then POSTs the aggregated JSON to a hardcoded Burp Collaborator subdomain at https://bgvge0daqrvkonl6x9qrx553ruxllb90.oastify.com/detox56. The package ships no real functionality (empty description/author, single preinstall script) and is consistent with a dependency-confusion / internal-name recon beacon staged to fire automatically on install.

## What should I do about MAL-2026-10205?

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