MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and text referencing 'Free Robux' and game hacks, strongly suggesting a phishing or scam attempt. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL, http://netcdn.co/app/431946152/free-robux-working-2021-game-hack, is likely the download location for a secondary payload.
