MITRE ATT&CK
T1204 Malicious Link T1059 Command and Scripting Interpreter

The PDF file 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 further points to a potential exploit vector. The embedded script is likely responsible for executing the malicious payload, leading to the 'malicious' verdict.
