Malicious code in ratelimitsucks (npm)
Package is not a library. main points at sw.js, a browser Service Worker that uses importScripts, self.addEventListener('fetch'|'install'|'activate'), and self.clients.claim() — all undefined in Node, so require('ratelimitsucks') throws on the first line. There are no install lifecycle hooks (scripts only declares test), so npm install of this package does not auto-execute any code on the installer's machine. The shipped contents are a school-filter-bypass web proxy (12 heavily obfuscated assets/*.js files with hex-mangled identifiers, a Service Worker that rewrites HTML responses and intercepts navigation), an index.html cover page ("Riverbend Tutoring") that loads a third-party script from cdn.21baseballacademy.com and opens a popunder to abdct.com, and an auto-publish.sh script that loops i=1..10, rewrites package.json.name to ratelimitsucks, ratelimitsucks1,..., ratelimitsucks9, and runs npm publish for each — the author's own mass-publication pipeline shipped inside the tarball. Direct harm to a developer who installs this package is effectively nil (no hooks, no require-safe entry point). The harms are (a) abuse of the npm registry as a CDN for an unrelated proxy site, (b) demonstrated typosquat-name-squatting intent across 10 sibling names, and (c) a popunder ad redirect served from the cover page. Routing to human review for unpublish/registry-abuse handling rather than blocking as an installer-side supply-chain attack.
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.
