T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual "download button" lure, strongly suggesting an attempt to trick the user into downloading a second-stage payload. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL points to a "free coin spin" offer, which is a common lure for game-related cheats or malware.
