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

The ML classifier strongly indicated maliciousness, and the document body contains numerous links to external resources, including one at 'http://netcdn.co/app/431946152/cch-ly-robux-free-2021-game-hack'. The presence of a heuristic for a visual download button further supports the conclusion that this PDF is designed to trick users into downloading unwanted applications, likely related to game hacks or cheats.
