T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The PDF document contains multiple embedded URLs and references to game hacks and free spins, strongly suggesting a lure for users to download potentially malicious software. The ML classifier also flagged this PDF with high confidence. The presence of external URIs and a call-to-action button further supports the malicious intent.
