T1204.002 Malicious File
The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. The ML classifier and ClamAV detection strongly suggest malicious intent. While the document body is unreadable, the presence of JavaScript points to an attempt to execute arbitrary code, likely to download and run a second-stage payload. The specific URLs extracted are related to XFA, a PDF form technology, but their reputation is unknown or benign, suggesting they are not the primary malicious indicators.
