MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for downloading the game Minecraft, directing users to a malicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the document's structure and embedded links suggest a phishing or malware distribution attempt.

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