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.Exploit.Agent-36014' strongly suggests this JavaScript is malicious. The extracted artifact 'javascript_obj0013_001.js' and the heuristic 'Suspicious extracted artifact' with signals like 'Hex escape obfuscation' and 'Script obfuscation indicators' further support that the embedded script is designed to perform malicious actions, likely downloading and executing a second-stage payload.
