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

The PDF file contains an embedded malicious object that exploits CVE-2010-0188 in Adobe Reader. This exploit is designed to download and execute a secondary payload, as indicated by the ClamAV detection 'Pdf.Exploit.Dropped-90' and the presence of an embedded file. The document body itself does not contain user-facing text, suggesting its primary purpose is exploit delivery.
