MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the presence of an embedded PDF script artifact. The ML classifier and ClamAV detection strongly suggest malicious intent, likely involving the execution of JavaScript to exploit a vulnerability. The XFA form detected also points to a complex PDF structure often used for exploitation.
