MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is a PDF file that contains an embedded XFA form. Static analysis identified a critical heuristic firing for CVE-2010-0188, an Adobe Reader LibTIFF XFA image exploit. This indicates the file is designed to exploit this vulnerability to achieve code execution. The embedded URL is likely related to the XFA template but does not appear to be a direct payload delivery mechanism.
