MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a "download button" heuristic, strongly suggesting it is designed to trick users into downloading a second-stage payload. The document body and URLs explicitly mention game hacks and free in-game currency, indicating a social engineering lure. The ML classifier also flagged this PDF as malicious with high confidence.
