T1059.001 PowerShell
T1204.002 Malicious File
The file is identified as malicious by ClamAV (Js.Exploit.HTML-30) and a machine learning classifier. It utilizes XFA forms, a known vector for PDF exploits. The embedded URL, while not directly executable, points to an XFA schema, suggesting the form's structure is intended to facilitate exploitation. The presence of JavaScript within the PDF structure, indicated by the ClamAV detection and ML flagging, strongly suggests an attempt to execute malicious code upon opening.
