MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains numerous URLs related to game hacks and free currency, strongly suggesting a lure for users to download malicious content. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme indicate an attempt to trick users into downloading a second-stage payload.
