MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises free in-game items and hacks for popular games like Roblox. The primary external URI, http://netcdn.co/app/431946152/free-roblox-merch-game-hack, is likely a landing page for downloading a malicious payload. The ML classifier strongly flagged this PDF as malicious, supporting the conclusion that it is designed to trick users into downloading malware.
