The PDF document contains a lure for a "Coin Master Free Spins Hack" and directs the user to a URL that likely hosts a malicious application. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to trick users into downloading unwanted software. No scripts were extracted from this sample.
