MITRE ATT&CK
T1204.002 Malicious File T1559.001 Component Object Model Hijacking

The PDF file contains an embedded XFA form with a critical heuristic firing for CVE-2010-0188, indicating an exploit targeting Adobe Reader's LibTIFF component. This exploit likely delivers a second-stage payload, as suggested by the 'Pdf.Exploit.Dropped-90' ClamAV detection and the presence of an embedded binary artifact. The document body is unreadable, but the exploit and embedded file are sufficient indicators of malicious intent.
