passkeys-react @1.0.1

Summary

package.json declares a preinstall hook that runs index.js on npm install. The script collects hostname, username, home directory, DNS servers, current working directory, and the contents of /etc/passwd and /etc/hosts, then POSTs the collected data over HTTPS to the hardcoded subdomain ltivq9rn7t7gkxho4o1micsk6bc20uoj.oastify.com (a Burp Collaborator out-of-band interaction host). The behavior fires automatically as part of a default install and matches an installer-side host reconnaissance and system-file exfiltration pattern; the package's stated purpose (a passkeys React helper) does not require reading /etc/passwd, /etc/hosts, or contacting an OAST endpoint.
