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

The PDF document contains numerous links, including one to 'netcdn.co', which likely serves as a lure for downloading malicious content related to game hacks and free currency. The ML classifier strongly flagged this PDF as malicious, supporting the assessment that it is designed to trick users into downloading potentially harmful files. The presence of a visual download button heuristic further reinforces this conclusion.
