MITRE ATT&CK

T1059.001 JavaScript/Shell Scripting: JavaScript

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including 'PDF_JAVASCRIPT' and 'PDF_JS'. ClamAV also detected it as 'Pdf.Exploit.Agent-36014'. The embedded JavaScript, found in 'javascript_obj0013_001.js', exhibits obfuscation, suggesting it is designed to download and execute a secondary payload. The exact nature of the payload cannot be determined due to obfuscation, leading to an unknown family classification and a slightly reduced confidence.
