MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.004 Command and Scripting Interpreter: PowerShell

The sample is a PDF file that exploits CVE-2010-0188, a vulnerability in Adobe Reader related to XFA forms. This exploit is designed to execute arbitrary code. The embedded URL, http://www.xfa.org/schema/xfa-template/2.5/, is likely part of the exploit chain, potentially used to download or host the malicious payload. The document body contains obfuscated JavaScript-like content which, combined with the XFA form structure, suggests an attempt to execute malicious code.
