MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detections for 'Pdf.Dropper.Agent-7286180-0' and 'Win.Trojan.Agent-36166' on an extracted artifact strongly suggest this PDF is a dropper. The embedded JavaScript is likely responsible for downloading and executing the secondary payload, which was detected as a trojan.
