MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains an embedded object that triggers the CVE-2010-0188 exploit, targeting Adobe Reader. This exploit is known to deliver a second-stage payload, indicated by the 'Pdf.Exploit.Dropped-90' ClamAV detection and the suspicious embedded file artifact. The document body is not readable, but the exploit and embedded file strongly suggest a malicious intent to execute arbitrary code.
