T1203 Exploitation for Client Execution T1059.001 PowerShell

The sample is a PDF document that contains an embedded file and triggers the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader related to LibTIFF XFA images, allowing for arbitrary code execution. The embedded file, named 'embedded_file_obj0001.bin', is likely the secondary payload. The document body content is heavily obfuscated and does not provide direct clues to the user-facing lure.
