MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment T1204 User Execution

The PDF file contains an embedded TIFF image payload that exploits the CVE-2010-0188 vulnerability in Adobe Reader's LibTIFF component. This exploit is designed to execute arbitrary code, likely leading to the download and execution of a second-stage payload. The ClamAV detection 'Pdf.Exploit.Dropped-90' further confirms its malicious nature.
