The PDF file contains embedded JavaScript and an XFA form, which are commonly used to deliver exploits. The critical heuristic firing indicates a match for CVE-2010-0188, an exploit targeting Adobe Reader's LibTIFF component. This exploit allows for arbitrary code execution, likely to download and run a second-stage payload.
