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, a common technique for hiding malicious code. The likely intent of the script is to exploit a vulnerability within the PDF reader to download and execute a secondary payload, which is a common attack vector for PDF-based malware.
