T1203 Exploitation for Client Execution

The critical heuristic firing for CVE-2010-0188 indicates that this PDF document is designed to exploit a vulnerability in Adobe Reader's LibTIFF component.

The embedded URL, while not directly malicious in reputation, is part of the exploit delivery mechanism.
