The sample is a PDF file that contains a critical heuristic firing for CVE_2008_2551, indicating an exploit for a downloader. The embedded URL points to a CAB file which likely contains an ActiveX control for exploitation.

The exploit likely aims to download and execute a second-stage payload from the artisanballoonz.com domain.
