The PDF contains numerous embedded URLs and a document body that explicitly mentions "Free Robux Scam" and links to various game-related hacks and cheats. The ML classifier also flagged this PDF as malicious. The presence of these lures suggests an attempt to trick users into visiting malicious sites, likely to download further malware or engage in credential harvesting.
