MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs that promise free in-game items for popular games, acting as a lure. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users. While no scripts were explicitly extracted, the document's structure and content suggest it's designed to trick users into clicking links that likely lead to further compromise.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
