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.json declares a preinstall lifecycle script that runs curl against the hardcoded bare IP http://109.71.252.153:8080/ at npm install time, sending the installer's OS (uname -s), username (whoami), working directory (pwd), and hostname as query-string parameters. The script fires automatically on `npm install` with no user interaction. The package ships only README and package.json — the declared `main: index.js` is absent and no ESLint functionality is provided — so the package's sole effect on the installer is the reconnaissance beacon. The name impersonates the ESLint plugin namespace (eslint-* / Angular / React), consistent with a typosquat/dependency-confusion lure aimed at developers searching for an ESLint plugin.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
