The PDF contains a large number of external links, many of which point to other PDF files, suggesting a link farm designed to distribute malware. The heuristic 'PDF_SEO_LINK_FARM' specifically flags this behavior. The primary malicious URL identified is http://esecuritys.com/VGhlRWxkZXJTY3JvbGxzVlNreXJpbVNwZWNpYWxFZGl0aW9uQ3JlYXRpb25DbHViRnJlZURvd25sb2FkVGh/ZG93bmxvYWR8V0gzWm5CMWJYeDhNVFkxTnpBMk56RTFOSHg4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk/attractiv/amcheck/inventions...gassing.nondestructive, which is likely a distribution point for malicious content.
