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

The PDF document contains numerous embedded URLs and a document body that promotes free in-game currency and cheats for popular games. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect users to download further malicious content. The document body's content, combined with the heuristics, indicates a lure for potentially unwanted or malicious downloads.
