T1566.001 Spearphishing Attachment

The PDF document contains text and embedded URLs related to 'free Robux hacks', strongly suggesting a scam or phishing lure. The ML classifier also flagged the PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the document's content indicate an attempt to redirect users to potentially harmful websites.
