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' strongly suggests a known exploit. The extracted JavaScript file exhibits obfuscation, typical of malware attempting to hide its payload. The primary attack pattern involves leveraging a PDF vulnerability to run this script, which likely downloads and executes a second-stage payload.
