MITRE ATT&CK

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

The PDF file contains an embedded script payload and utilizes XFA forms, which are known vectors for exploitation. ClamAV detection as 'Pdf.Exploit.Agent-6136306-0' strongly indicates malicious intent. The embedded script is likely responsible for executing the exploit, leading to the download or execution of a secondary payload. The presence of XFA suggests an attempt to leverage vulnerabilities within Adobe's XML Forms Architecture.
