MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one that directly advertises a 'free robux game hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of these links suggests an attempt to direct the user to a download site. The document body, though partially corrupted, also contains references to free Robux and game hacks, reinforcing the lure.
