MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and document body text referencing game hacks and cheats, strongly suggesting a social engineering lure. The ML classifier also flagged this PDF as malicious. The primary URL, http://netcdn.co/app/431946152/roblox-source-game-hack, likely hosts a secondary payload. No scripts were extracted, but the presence of external URIs and the ML classification indicate a high likelihood of malicious intent.
