T1566.001 Spearphishing Attachment
The PDF document contains numerous embedded links and a call-to-action phrase, directing users to websites offering 'free Robux' or 'free spins'. The heuristic PDF_SEO_LINK_FARM indicates a mass of external links, suggesting a link farm designed to attract users through deceptive offers. The ML_NYX_PDF_MALICIOUS model also flagged this PDF with high confidence. The primary IOC is the URL https://netcdn.xyz/app/431946152/free-robux-today-game-hack, which is likely the final destination for the scam.
