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

The PDF file contains an XFA form and exploits the CVE-2010-0188 vulnerability in Adobe Reader's LibTIFF component. This exploit is designed to execute arbitrary code, as indicated by the ClamAV detection 'Pdf.Exploit.Agent-36821'. The embedded URL, while seemingly benign, is often used in conjunction with such exploits to fetch and execute further malicious content. The document body contains obfuscated JavaScript-like code which likely contributes to the exploit chain.
