MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that promises free in-game currency, indicating a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it may download further malicious content. Although no scripts were explicitly extracted, the nature of the lures and the high ML score suggest a high likelihood of malicious intent.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
