MITRE ATT&CK
T1204.002 Malicious File T1059.001 PowerShell T1190 Exploit Public-Facing Application

The PDF file contains an embedded exploit targeting CVE-2010-0188 in Adobe Reader's LibTIFF component. 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 content appears to be obfuscated or corrupted, providing no direct clues about the lure.
