Malicious package

Published to npm · OSV MAL-2026-16111

What to do

Remove etoro-aggregator from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (d7d5f0fb8c06c23afad28686a3d3d689dfc5a3786c73bff2c569fd8b55f2b4ad) The package's preinstall.js lifecycle script executes automatically on `npm install` and performs reconnaissance on the installer host. It collects hostname, username, current working directory, platform, and the output of OS commands including `whoami /all`, `ipconfig /all` / `ifconfig`, `tasklist` / `ps aux`, directory listings of `/`, `C:\`, and the user's home, and a dump of environment variables. The collected data is transmitted via HTTP GET and POST to the hardcoded bare IP endpoint `http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/v4/...`. The package's declared main is an empty stub and its description ("Internal service client library") combined with the implausibly high version number `99.0.2` is consistent with a dependency-confusion attack targeting an internal `etoro-aggregator` name. The manifest plus the preinstall script constitute the entire payload; installing the package leaks installer host identity, network configuration, filesystem structure, and environment variables (which routinely contain credentials and tokens) to an attacker-controlled endpoint.

Impact

Installing this package leaks sensitive host environment information (hostname, username, current working directory) to an attacker-controlled server over unencrypted HTTP. This reconnaissance data can be used by attackers to identify and target specific organizations or users for further attacks. No direct code execution beyond the preinstall script is described, and no known exploits in the wild have been reported.

Defensive guidance

Users should avoid installing the etoro-aggregator package version 999.0.0. Organizations should audit their internal package names to prevent dependency confusion attacks and consider using scoped packages or private registries to mitigate such risks. Monitor for unexpected packages with suspicious names during dependency installation.

Summary

The etoro-aggregator npm package at version 999.0.0 includes a preinstall.js script that runs automatically on npm install. This script performs an HTTP GET request to a hardcoded attacker-controlled IP address (http://209.126.81.147/etoro-depconf-poce346552f776f/npm/<hostname>/<username>/<cwd>), sending system information such as os.hostname(), os.userInfo().username, and process.cwd() as URL path segments. The package name and version suggest it is a dependency-confusion attack vector, aiming to collect host identity information for targeted follow-on attacks. There is no legitimate library code in the package, confirming its malicious intent.
