T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent call-to-action related to 'Free Robux' and game hacking. The ML classifier strongly flagged this PDF as malicious, and the presence of numerous suspicious URLs suggests a phishing or malware distribution attempt. While no scripts were directly extracted, the document structure and embedded links indicate a likely attempt to redirect users to malicious sites.
