MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates this PDF is recognized as a known exploit (Pdf.Exploit.Agent-36014). Low-severity heuristics confirm the presence of JavaScript actions and embedded JS streams within the PDF structure. An extracted JavaScript file, 'javascript_obj0013_001.js', was also flagged for suspicious characteristics like hex escape obfuscation. The combination of these factors strongly suggests the PDF is designed to leverage these JavaScript components to execute malicious code, likely downloading and running a secondary payload.
