MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a heuristic firing for an external URI, all related to "Robux" and "hacks", suggesting a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious. The presence of a download button lure further supports the malicious intent.
