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

The sample is a PDF file that triggers a critical heuristic for CVE-2010-0188, an exploit targeting Adobe Reader's XFA form processing. This indicates the file is designed to execute arbitrary code upon opening. The embedded URL, while seemingly benign, is associated with XFA templates and could be a lure or part of the exploit chain. No scripts were extracted from this sample, but the exploit itself is the primary mechanism for delivering a payload.
