MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is a PDF file that contains an embedded XFA form. Heuristics indicate it exploits CVE-2010-0188, a vulnerability in Adobe Reader's handling of XFA forms. This exploit is designed to execute arbitrary code on the victim's machine. The embedded URL is likely related to the XFA template but does not appear to be a direct payload delivery mechanism.
