MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body and embedded URLs advertise a "Coin Master Hack", suggesting a lure to download a malicious application. While no scripts were directly extracted, the presence of embedded URLs and the nature of the lure indicate a high likelihood of malicious intent, potentially involving a downloader or exploit.

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.
