T1059.001 JavaScript/JScript
T1204.002 Malicious File
The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including 'PDF_JAVASCRIPT' and 'PDF_JS'. The ClamAV detection 'Heuristics.PDF.ObfuscatedNameObject' further supports its malicious nature. The embedded JavaScript is likely responsible for executing malicious actions, such as downloading and running additional payloads, which is a common technique for PDF-based malware delivery. The presence of XFA form elements also suggests a complex document structure potentially used to hide malicious content.
