MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one at http://netcdn.co/app/431946152/roblox-arsenal-cheat-2021-game-hack, which is likely intended to deliver a payload. The document's content and the ML classifier's high confidence score indicate a malicious intent to trick users into downloading unwanted software. No scripts were extracted, but the presence of external links and the lure of game cheats suggest a downloader or trojan distribution pattern.
