MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that explicitly advertises hacks and cheats for popular games like Roblox and Coin Master. The primary external URI, http://netcdn.co/app/431946152/dex-ex-roblox-hack-game-hack, likely hosts a malicious payload. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent.
