MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, with a primary external URI pointing to a download link for game-related cheats. The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of it serving as a lure for malware distribution. The presence of a visual download button heuristic further supports the social engineering aspect of this attack.
