MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains embedded URLs and text that explicitly promote downloading hacks for popular games like Roblox and Coin Master. The primary external URL, http://netcdn.co/app/431946152/create-a-magic-roblox-hacks-game-hack, likely hosts a malicious payload. The ML classifier also strongly indicated maliciousness, supporting the conclusion that this document is a lure for downloading potentially harmful software.
