MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF document contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the presence of an embedded artifact. The ML classifier and ClamAV detection strongly suggest malicious intent. The XFA form structure is also noted. The embedded script is likely responsible for executing the malicious payload, potentially leading to further compromise.
