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.Dropper.Agent-7212078-0' strongly suggests this is a dropper. The JavaScript is likely responsible for downloading and executing a secondary payload, which is a common technique for malware delivery. The document body contains a large amount of seemingly random text, which is often used to obscure the malicious content or to bypass simple content filters.
