It collects host identifiers (hostname, platform, architecture, kernel release, uid/gid, CPU count, memory) and internal network interface addresses, base64-encodes the payload, and POSTs it over plain HTTP to the hardcoded subdomain vml73pdk3ft3t434ssjycv4khbn2btzi.oastify.com — a Burp Collaborator (OAST) callback host used to confirm code execution on the installer.
