The PDF document contains a large number of external links, indicative of a link farm designed to redirect users to malicious content. One prominent URL, http://evacdir.com/devastated/lathes.ZG93bmxvYWR8OWFIYmpKMmRYeDhNVFkxTkRnNU16RTVNWHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA/measly/MTIgdGVuc2VzIGluIHVyZHUgcGRmIGRvd25sb2FkMTI.nidhi?grownup, is directly embedded and likely serves as a primary download source. The heuristic 'PDF_SEO_LINK_FARM' further supports this, identifying a mass of external PDF links.
