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

The PDF file contains XFA form data and triggers a critical heuristic for CVE-2010-0188, indicating exploitation of Adobe Reader. ClamAV also detected it as Js.Exploit.HTML-30. The embedded URL is likely related to the exploit delivery mechanism. The script content, though obfuscated, suggests JavaScript execution which is often used to download and execute further stages.
