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

The PDF document contains an embedded URL that directs users to a site offering a 'free Robux game hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button lure reinforces the deceptive nature of the document. The primary goal appears to be tricking users into downloading a second-stage payload.
