T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates the file is recognized as a PDF exploit (Pdf.Exploit.Agent-36142). Low-level heuristics also confirm the presence of embedded JavaScript within the PDF structure. While the document body is unreadable, the presence of JavaScript actions and streams strongly suggests that the PDF is designed to leverage these elements to execute malicious code, likely downloading and running a secondary payload.
