MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, many of which point to resources related to game hacks and cheats, suggesting a lure for users to download potentially malicious files. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent. Although no scripts were extracted, the document's structure and content indicate it is designed to trick users into downloading a second-stage payload.

  • 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.
