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 suggests malicious intent. While the document body is heavily obfuscated and unreadable, the presence of JavaScript points towards an attack pattern involving the exploitation of PDF vulnerabilities to execute arbitrary code. The embedded URLs are related to XFA forms, which can be a vector for such attacks. No specific malware family could be identified.
