MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for game hacks and free virtual currency, directing users to external URLs for downloads. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest it is designed to trick users into downloading and executing further malicious content.

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.
