MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous links to external websites, many of which are related to game hacks and free in-game currency, suggesting a lure for users to download potentially malicious files. The ML classifier strongly flagged this PDF as malicious, and the presence of a 'download button' heuristic further supports a malicious workflow. The document body explicitly mentions 'Free Generator For Robux' and includes the primary malicious URL.
