The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the ML_NYX_PDF_MALICIOUS classifier. ClamAV also detected it as Pdf.Exploit.Agent-6136306-0. The XFA form suggests a potential attack vector leveraging Adobe's XML Forms Architecture. The embedded script is likely responsible for executing malicious actions, potentially downloading further payloads.
