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

The sample is a PDF document that contains an embedded file and triggers the CVE-2010-0188 exploit. This indicates that the document is designed to leverage a vulnerability in Adobe Reader to execute arbitrary code. The embedded file, named 'embedded_file_obj0001.bin', is likely the malicious payload delivered by the exploit. The ClamAV detection 'Pdf.Exploit.Dropped-90' further confirms the malicious nature of the file.
