T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, many of which are related to 'free Robux' or game hacks, suggesting a phishing or malware distribution lure. The ML classifier also flagged this PDF as malicious with high confidence. The presence of a 'download button' heuristic further supports the interpretation that the document is designed to trick users into downloading further malicious content.
