MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious File

The PDF file contains an embedded XFA form that exploits the CVE-2010-0188 vulnerability in Adobe Reader. This exploit is designed to drop a secondary payload, indicated by the 'Pdf.Exploit.Dropped-90' ClamAV detection and the presence of an embedded binary file. The document body is unreadable, but the exploit and embedded artifact strongly suggest a malicious intent to compromise the user's system.
