MITRE ATT&CK

T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The CLAMAV_DETECTION heuristic further confirms its malicious nature, identifying it as Pdf.Exploit.Agent-36014. The embedded JavaScript, named javascript_obj0013_001.js, is flagged for suspicious obfuscation, suggesting it's designed to download and execute a secondary payload or perform other malicious actions. The exact intent of the script is unclear due to obfuscation, but its presence within a PDF exploit points to a delivery mechanism for further compromise.
