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 critical ClamAV detection (Pdf.Exploit.Agent-36014) and the suspicious extracted artifact (javascript_obj0013_001.js) with obfuscation indicators strongly suggest this is a malicious PDF exploiting a vulnerability. The embedded JavaScript is likely designed to download and execute a secondary payload, a common technique for initial access.
