MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains an external URI pointing to a suspicious download link, and a machine learning classifier flagged it as malicious with high confidence. The document body and embedded URLs suggest a lure for game-related cheats or hacks, which is a common pretext for malware distribution. Although no scripts were explicitly extracted, the presence of external links and the ML detection strongly indicate a malicious intent to deliver a payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

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.
