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

The document contains numerous links to external websites, with one prominent URL pointing to a download for 'roblox-free-items-2021-game-hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent. The primary goal appears to be tricking the user into downloading a secondary payload disguised as a game hack or cheat tool.
