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. ClamAV detection as 'Pdf.Exploit.Agent-36014' confirms its malicious nature. The embedded JavaScript, extracted as 'javascript_obj0013_001.js', likely contains obfuscated code designed to exploit a vulnerability within the PDF reader, potentially leading to further malicious activity. The document body is unreadable, so the rationale is based on the heuristics and embedded script.
