MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that advertises game hacks and cheats, aiming to trick users into downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests a download attempt. No scripts were extracted from this sample, limiting the ability to determine specific execution or persistence mechanisms.

  • 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.
