package.json declares postinstall: node index.js, causing index.js to execute automatically on npm install. The script collects the installer's OS username (os.userInfo().username), current working directory (process.cwd()), hostname (os.hostname()), and non-internal IPv4 address (derived from os.networkInterfaces()), then POSTs them as a JSON body to a hardcoded webhook.site endpoint controlled by the author. The package has no legitimate library functionality — its only file is the beacon, its description is empty, and it declares a self-referential dependency on itself. Installing this package leaks installer host identifiers to an attacker-controlled collector.

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.
