MITRE ATT&CK
T1204.002 Malicious File

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 execute arbitrary code, and the ClamAV detection 'Pdf.Exploit.Dropped-90' indicates that this file is a known dropper for further malicious activity. The embedded file 'embedded_file_obj0001.bin' is likely the secondary payload.
