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 heuristic flags it as Pdf.Exploit.Dropped-94, suggesting it's a known exploit dropper. The embedded JavaScript is likely responsible for downloading and executing a secondary payload, which is a common attack pattern for such files. The large size of the embedded JavaScript object (45640 bytes) further supports the complexity of the malicious action.
