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

The PDF document contains numerous links to external websites, including one that directly advertises a "gun hack" for Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious download. The document body's content and the embedded URLs indicate a lure for game-related cheats or hacks, likely leading to malware.
