What it does
The package runs node index.js from its postinstall script. The script sends an HTTPS POST request to https://nathanaccacio.com/collect with a JSON body holding the package name, the operating-system user name and the host name of the machine that installed it. It does nothing else.
Impact: the operator of nathanaccacio.com learns which users and hosts install the package.
Remediation: remove the package from all projects and lockfiles and review the hosts that installed it.

What to do if you installed it
- Remove the package from every project that uses it, directly or through another dependency.
- Pin a clean version if you need the package: one that is not listed above and that you have checked yourself, or replace the package. A version missing from this page is not cleared.
- Check your lockfiles (
package-lock.json,yarn.lock,pnpm-lock.yaml) for the affected versions, including as a transitive dependency, and in CI caches. - Rotate credentials that were reachable from any machine or build that installed it: npm and GitHub tokens, cloud keys, SSH keys, and secrets in environment variables or CI settings.
