MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. The critical ClamAV detection as Pdf.Exploit.Agent-36014 further supports malicious intent. An extracted JavaScript file, javascript_obj0013_001.js, shows signs of obfuscation, suggesting it is designed to perform malicious actions such as downloading and executing a second-stage payload. The document body content is unreadable, but the presence of JavaScript and the ClamAV signature strongly indicate an exploit attempt.
