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 and the presence of an embedded artifact. ClamAV detection as 'Pdf.Exploit.Agent-6136306-0' strongly suggests exploitation of a known PDF vulnerability. The XFA form heuristic further points to a potential attack vector leveraging Adobe's XML Forms Architecture. The embedded script is likely responsible for downloading and executing a second-stage payload.

Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
