MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is a PDF file that contains an XFA form, which is a known vector for exploiting Adobe Reader vulnerabilities. Specifically, the CVE-2010-0188 heuristic indicates exploitation of the LibTIFF component within Adobe Reader. The embedded URL is likely related to the XFA template, but its reputation is unknown. The heuristic firings and the presence of an embedded URL strongly suggest this PDF is designed to exploit a vulnerability and execute a payload.
