Analysis

The package's preinstall hook runs index.js, which collects system information from the installer's machine — hostname, username, home directory, DNS servers, and the contents of /etc/passwd and /etc/hosts — and POSTs this data as JSON to the remote host vjib8dmg59zuxwwymzboy0ymhdn4bvzk[.]oastify[.]com:443 (a Burp Collaborator endpoint). The data exfiltration runs automatically at install time.
