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 specifically flags 'javascript_obj0013_001.js' as suspicious due to hex escape and script obfuscation. ClamAV also detected the file as 'Pdf.Exploit.Agent-36014'. The presence of obfuscated JavaScript strongly suggests an attempt to download and execute a second-stage payload, a common technique for exploiting PDF vulnerabilities.
