Description
The npm package ratelimitsucks6 (version 1.1.7) is a malicious package that is part of an auto-published family of similarly named packages. It contains heavily obfuscated JavaScript code that acts as a browser-side proxy and redirector, loading third-party scripts and opening external URLs upon user interaction. The package does not execute automatically on install or require, but its presence indicates registry pollution and namespace abuse. Installing or running this package may lead to full system compromise.
