MITRE ATT&CK
T1204 Malicious File T1204.002 Malicious File: User Execution: Malicious File

The PDF file contains an embedded malicious object that exploits the CVE-2010-0188 vulnerability in Adobe Reader. This exploit is designed to download and execute a secondary payload, as indicated by the 'Pdf.Exploit.Dropped-90' ClamAV detection and the presence of an embedded file. The document body is not human-readable, suggesting it is primarily a container for the exploit.
