The PDF document contains a large number of external links, many of which point to other PDF files. One of the embedded URLs, 'http://drobgyn.net/uploads/1/3/0/4/130488506/130488506.html#add+java+to+path+windows+7+64+bit+download+oracle', suggests a lure related to software installation. The heuristic 'PDF_SEO_LINK_FARM' indicates a technique to generate many links, likely for SEO manipulation or to host malicious content. No scripts were extracted from this sample.
