MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript that utilizes eval() calls, indicating an attempt to execute arbitrary code. The ClamAV detection 'Pdf.Exploit.Agent-36118' and the heuristic firing for 'PDF_EVAL' strongly suggest a PDF exploit. The embedded JavaScript stream, named 'javascript_obj0013_000.js', is likely responsible for the malicious payload delivery. The document body contains obfuscated JavaScript, making it difficult to determine the exact payload or its ultimate destination without further dynamic analysis.
