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

The ML classifier strongly flagged this PDF as malicious. The document body and extracted URLs indicate a lure for free Robux or game hacks, directing users to download an application from `http://netcdn.co/app/431946152/wahoogaming-co-free-robux-game-hack`. This pattern suggests the file is a malicious document designed to trick users into downloading and executing potentially harmful software.
