MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including 'PDF_JAVASCRIPT' and 'PDF_JS'. The 'EXTRACTED_FILE_STATIC_TRIAGE' heuristic flags suspicious characteristics like hex escape obfuscation and script obfuscation within the extracted 'javascript_obj0013_001.js' file. The ClamAV detection 'Pdf.Exploit.Agent-36014' further confirms its malicious nature. The embedded JavaScript likely attempts to exploit a PDF vulnerability to download and execute a second-stage payload.
