🛡️ MAL-2026-10214 — babel-preset-lib-client

Malicious code in babel-preset-lib-client (npm)

Source: amazon-inspector

index.js, the package main, runs a load-time IIFE that collects OS platform and architecture, hostname, username, private and public IP (via https://api.ipify.org), current working directory, the full output of printenv (base64-encoded), and the base64-encoded output of tree../, then POSTs the aggregated payload to a hardcoded Discord webhook at https://discord.com/api/webhooks/1524917003394089029/. The package name mimics the babel-preset naming convention but the code implements no Babel functionality; author, description, and keywords are empty. Any consumer that installs and requires this package leaks its full process environment (typically including NPM_TOKEN, AWS_*, GITHUB_TOKEN, and other CI/developer secrets) plus a listing of the parent directory to the attacker-controlled Discord channel.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
