The PDF document contains numerous links to external websites, many of which appear to be part of a link farm designed to host SEO-optimized PDF files. One prominent URL, http://netcdn.tw/app/406889139/coin-master-hack-app-ios-game-hack, suggests a lure for downloading a game hack application. The ML classifier also strongly indicated maliciousness.
