MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual call-to-action, strongly suggesting it is designed to trick users into downloading a malicious payload. The ML classifier also flagged this PDF with high confidence. The primary malicious URL identified is http://netcdn.co/app/431946152/free-roblox-jpg-game-hack, which likely hosts the secondary stage.
