MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to "hacking" for game currency, directing users to an external URL. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the overall structure and content suggest a phishing or social engineering attempt.

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