The PDF file contains XFA form elements and embedded JavaScript, as indicated by the PDF_XFA heuristic and the CLAMAV_DETECTION rule firing for Js.Exploit.HTML-30. The embedded JavaScript is likely responsible for exploiting a vulnerability within the PDF reader to download and execute a secondary payload. The embedded URL was identified but has an unknown reputation.
