The PDF document contains numerous embedded URLs pointing to external files, a technique commonly used for SEO link farming and distributing malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button lure further supports a malicious intent. The primary URL http://netcdn.tw/app/406889139/coin-master-daily-gifts-game-hack likely serves as the initial download point for a secondary payload.
