# MAL-2026-16115: Malicious code in etoro-billing (npm)


- **Type:** Malicious package
- **Package:** `etoro-billing` (npm)
- **Published:** 10 Sep 2026

## What is MAL-2026-16115?

MAL-2026-16115 is a malicious package in etoro-billing, published on 10 Sep 2026. 

### Official description

On `npm install`, the package's `preinstall` lifecycle hook executes `preinstall.js`, which reads `os.hostname()`, `os.userInfo().username`, and `process.cwd()` and issues an HTTP GET to `http://209.126.81.147/etoro-depconf-poce346552f776f/npm/<hostname>/<username>/<cwd>`. The destination is a hardcoded bare-IP over plain HTTP, unrelated to any documented eToro infrastructure. `index.js` is an empty stub (`module.exports = {}`), so the only effect of installing this package is the identifier beacon. The package name claims eToro affiliation and is published as version 999.0.0, a high-version pattern used to win resolution against an internal package of the same name (dependency confusion).

## What should I do about MAL-2026-16115?

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