T1203 Exploitation for Client Execution T1059.001 PowerShell

The sample is a PDF file that triggers the CVE-2010-0188 exploit, which targets Adobe Reader's LibTIFF component. This exploit allows for arbitrary code execution. The presence of an embedded file and XFA form further indicates malicious intent. While no specific family is identified, the exploit suggests a downloader or dropper mechanism.
