MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests an exploit is present. The extracted JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation, typical of malware attempting to hide its malicious actions. The script likely downloads and executes a second-stage payload, contributing to the overall malicious nature of the PDF.
