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. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests a known exploit. The extracted JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation, typical for malware attempting to download and execute further stages. The lack of readable document body text means the primary indicators are the embedded script and the exploit detection.
