MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for free game spins, directing users to a suspicious URL. The ML classifier flagged this PDF as malicious with high confidence. Although no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest an attempt to download a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8948

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.
