# MAL-2026-16120: Malicious code in etoro-core (npm)


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

## What is MAL-2026-16120?

MAL-2026-16120 is a malicious package in etoro-core, published on 10 Sep 2026. 

### Official description

The package's preinstall lifecycle script (preinstall.js) issues an HTTP GET to the hardcoded bare-IP endpoint http://209.126.81.147/etoro-depconf-poce346552f776f/npm/ with os.hostname(), os.userInfo().username, and process.cwd() embedded in the URL path. This runs automatically on `npm install` and transmits installer host identity over plaintext HTTP to an attacker-controlled destination. The package name and inflated 999.0.0 version are consistent with a dependency-confusion payload targeting an internal `etoro-core` name.

## What should I do about MAL-2026-16120?

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