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 `preinstall: node index.js`, which fires automatically on `npm install`. index.js collects hostname (os.hostname()), username (os.userInfo()), homedir, DNS servers, and package paths, reads /etc/passwd and /etc/hosts via fs.readFileSync, and HTTPS-POSTs the JSON payload to 66az91mywqmmbqau9k79bum1us0jo9cy.oastify.com (a Burp Collaborator subdomain). Package metadata (empty author, empty description, generic CI-flavored name `ebpf-tracker-action`) is consistent with a dependency-confusion attack targeting an internal package name. Any machine that installs this package leaks system identity and local account data to an attacker-controlled host at install time.
