MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious PDF T1566.002 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the ClamAV detection of Pdf.Exploit.Agent-6136306-0. The presence of XFA form elements further suggests a complex PDF structure often used for exploitation. The embedded script is likely responsible for downloading and executing a second-stage payload, contributing to the malicious nature of the document.
