The sample is a PDF file that contains an XFA form, which is leveraged to exploit CVE-2010-0188 in Adobe Reader. The heuristic firings indicate a critical exploit targeting this vulnerability. The embedded URL is likely related to the XFA template, but no further malicious activity was directly observed from it. The document body appears to be obfuscated JavaScript, likely part of the exploit chain.
