Description

The npm package axios-fast versions 1.0.0 and 1.0.1 contains malicious code that executes during installation. Specifically, a preinstall script sends all environment variables from the installing machine to an attacker-controlled webhook URL. This can expose sensitive secrets such as AWS credentials, NPM tokens, and GitHub tokens. The package is a typosquat of the popular axios HTTP client and does not provide legitimate functionality beyond this exfiltration.

Impact

Installation of axios-fast versions 1.0.0 or 1.0.1 can lead to the disclosure of all environment variables on the host machine to a third party. This includes sensitive credentials and tokens commonly used in continuous integration and deployment pipelines, potentially leading to unauthorized access to cloud resources, package repositories, and source code management systems.

Defensive guidance

Avoid using the axios-fast package entirely. Since this is a malicious package, the best mitigation is to remove it from any dependency trees and replace it with the legitimate axios package or other trusted alternatives. Rotate any credentials that may have been exposed if this package was installed.

Summary

The axios-fast package versions 1.0.0 and 1.0.1 include a preinstall lifecycle script that runs automatically during npm install. This script executes a Node.js one-liner that posts the entire process environment variables to a hardcoded webhook.site URL controlled by an attacker. This behavior results in the exfiltration of potentially sensitive environment variables, including CI/build secrets like AWS_*, NPM_TOKEN, and GH_TOKEN. The package is malicious and designed to harvest secrets rather than provide useful functionality.
