MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that promotes 'free game packs' and 'hacks' for popular games, strongly suggesting a lure for users to download malicious content. The ML classifier also flagged this PDF as malicious with high confidence. The presence of embedded URLs and the nature of the lures indicate a likely attempt to deliver a second-stage payload, potentially via a drive-by download or by tricking the user into executing a downloaded file.
