T1203 Exploitation for Client Execution
The PDF contains a large number of embedded links pointing to other PDF files, many of which appear to be SEO-optimized lures for game-related cheats and free currency. The ML classifier strongly flagged this PDF as malicious, and the presence of a link farm suggests an attempt to direct users to potentially harmful content or downloads. The document body, though heavily obfuscated, contains a URL that aligns with the overall theme of game-related exploits.
