MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that suggest it is a lure for downloading a game hack. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URLs reinforces the suspicion of a download attempt. No scripts were extracted, but the overall structure and content point towards a social engineering attack.
