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

The PDF document contains multiple embedded URLs, with a primary external URI pointing to a download link for game-related hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent. The document likely serves as a lure to direct users to download potentially harmful files.
