MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV also flagged it as Heuristics.PDF.ObfuscatedNameObject, suggesting malicious intent. The embedded JavaScript likely downloads and executes a second-stage payload, though its exact function is obscured. The presence of XFA form elements further supports the possibility of complex, potentially malicious, document structures.
