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

The PDF document contains numerous embedded URLs and a document body that promotes game hacks and exploits, specifically for Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to download further content. The primary IOC is the URL http://netcdn.co/app/431946152/jailbreak-hack-roblox-script-game-hack, which is likely the intended download destination.
