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

The PDF document contains numerous links to external websites, many of which are disguised as downloads for game hacks and cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of these links suggests an attempt to trick users into downloading further malware. The document body explicitly mentions 'free Robux' and 'game hack', reinforcing the lure.
