T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious Link

The PDF document contains numerous embedded URLs and a prominent link in the document body, all directing users to websites that promise free items or hacks for popular games. The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of it being part of a phishing or scam campaign. The presence of a 'Download Now' type phrase further supports the lure.
