MITRE ATT&CK

T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The critical ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests this is a known exploit. The extracted JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation, typical of malware attempting to download and execute a second-stage payload. The exact intent of the script cannot be fully determined due to obfuscation, lowering confidence.
