The sample is a PDF document that contains embedded XFA (XML Forms Architecture) content. Heuristics indicate a critical vulnerability, CVE-2010-0188, which is an exploit targeting Adobe Reader's LibTIFF component when processing XFA forms. The embedded script, though obfuscated, appears to be JavaScript responsible for deobfuscating and executing the exploit payload. The presence of an embedded URL further suggests a download mechanism for a secondary stage.
