T1566.001 Spearphishing Attachment
The PDF document contains numerous embedded URLs and a document body that explicitly promises free in-game currency, such as 'Robux' and 'Coin Master spins'. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, and the ML classifier strongly flagged this PDF as malicious. The primary attack pattern involves luring users to malicious websites via these links, likely for credential harvesting or further malware distribution.
