MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains an embedded XFA form that triggers the CVE-2010-0188 exploit in Adobe Reader. This exploit is known to be used for arbitrary code execution. The embedded URL is likely related to the XFA template but does not appear to be a direct payload delivery URL. No scripts were extracted, but the exploit itself is sufficient to classify the attack pattern.
