MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure to download hacking tools for online games, evidenced by the document body and embedded URLs. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious site. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a phishing or social engineering attack.

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