MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection (Pdf.Exploit.Agent-36014) and the suspicious extracted artifact (javascript_obj0013_001.js) further confirm its malicious nature. The JavaScript is likely responsible for executing the exploit, leading to the malicious verdict. The exact behavior of the script is not fully discernible due to obfuscation, but it is the primary mechanism for exploitation.
