MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.xyz', which is likely a lure for downloading game-related cheats or hacks. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of external URIs and the document's deceptive content suggest an attempt to trick users into downloading further malicious content, potentially via a drive-by download or a malicious attachment.

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