MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains an embedded script payload, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. ClamAV also detected it as Pdf.Exploit.Agent-6136306-0, suggesting it's a known exploit. The embedded script is likely responsible for downloading and executing a second-stage payload, which is a common technique for initial infection. The XFA form detected by PDF_XFA is often used as a vector for embedding malicious content.
