MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detection as 'Pdf.Exploit.Agent-36174' strongly suggests this is a malicious PDF exploiting a known vulnerability. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, although its exact function cannot be determined due to obfuscation.
