T1566.001 Spearphishing Attachment
The PDF document contains numerous embedded links, identified as a link farm, that direct users to websites promising free Robux or Coin Master spins. The ML classifier and PDF heuristics strongly indicate malicious intent, likely to lead users to scam pages or download further malware. Although no scripts were explicitly extracted, the PDF structure and embedded URLs suggest a phishing or scamming attack.
