MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The critical ClamAV detection and the suspicious extracted artifact 'javascript_obj0013_001.js' with 'Hex escape obfuscation, Script obfuscation indicators' further confirm malicious intent. The embedded JavaScript is likely responsible for exploiting a PDF vulnerability to achieve arbitrary code execution, as suggested by the 'Pdf.Exploit.Agent-36014' ClamAV signature.
