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

The PDF document contains embedded URLs and a document body that explicitly advertises free hacks for the game Roblox. The primary URL, http://netcdn.co/app/431946152/roblox-online-play-free-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 malware.
