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

The PDF file contains an embedded XFA form that triggers the CVE-2010-0188 exploit, targeting a vulnerability in Adobe Reader's LibTIFF processing. 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 a suspicious embedded binary artifact. The document body content is not human-readable and appears to be obfuscated or corrupted data, providing no direct clues to the lure.
