The sample is a PDF document that utilizes XFA forms and exploits CVE-2010-0188, a known vulnerability in Adobe Reader's handling of LibTIFF images within XFA content. ClamAV also identified it as Pdf.Exploit.Dropped-78. The embedded URL, while seemingly benign, is part of the exploit structure. The script content is too fragmented to determine its exact function, but the exploit itself is the primary threat.
