T1204.002 Malicious File
The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including 'PDF_JAVASCRIPT' and 'PDF_JS'. The ML classifier strongly flagged this PDF as malicious. While the document body is unreadable, the presence of JavaScript suggests an attempt to execute code, likely to download and run a second-stage payload. The specific URLs extracted are related to XFA schemas but do not appear to be directly malicious.
