MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The critical heuristic firing indicates exploitation of CVE-2010-0188, a known vulnerability in Adobe Reader related to LibTIFF XFA images. This suggests the PDF is designed to execute code upon opening. The embedded file and XFA form further support this. While no specific script was extracted, the exploit likely facilitates the download and execution of a second-stage payload.
