MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for game-related cheats and hosting, directing users to a URL that likely serves a secondary payload. The ML classifier strongly flagged this PDF as malicious, and the embedded URL is highly suspicious. While no scripts were explicitly extracted, the PDF structure and embedded URI suggest an attempt to trick users into downloading malware.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
