Description
The npm package 'ratelimitsucks' version 1.7.7 contains malicious code primarily serving as a school-filter-bypass web proxy with obfuscated JavaScript files and a service worker. It includes a cover page that loads a third-party script and opens a popunder ad redirect. The package also contains a script for mass publication of typosquatted sibling package names. While it does not execute code on installation or when required in Node.js, it abuses the npm registry for hosting unrelated proxy content and advertising. The package poses a high risk if installed or run, as it may compromise the host system.
