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

The sample is a PDF file that contains an XFA form and exploits CVE-2010-0188, a vulnerability in Adobe Reader's handling of LibTIFF images within XFA forms. This exploit is designed to execute arbitrary code. The embedded URL, while seemingly benign, is part of the XFA structure and likely related to the exploit's delivery mechanism. No scripts were extracted, but the exploit itself indicates a malicious intent to compromise the user's system.
