The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.co', which are likely intended to lead users to download malicious applications or exploit kits. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent to trick users into downloading unwanted software.
