On npm install, the package's preinstall script runs index.js which collects the installer's hostname, platform, architecture, home directory path, and configured DNS servers, then POSTs them via HTTPS to t4ygm1p2e1grblohe7f7nlf0krqjef24.oastify.com/hit (a Burp Suite Collaborator subdomain used as an attacker-controlled callback endpoint). The package self-describes as a dependency-confusion proof of concept; installation causes automatic exfiltration of host reconnaissance data to a third-party endpoint before any user code runs.

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.
