MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains lures related to hacking and free in-game currency, directing users to external URLs. The presence of a 'ML_NYX_PDF_MALICIOUS' heuristic firing and a 'SE_MFA_LURE' suggests a credential harvesting or scam attempt. While no scripts were explicitly extracted, the PDF structure and embedded URLs indicate a malicious workflow designed to trick users into visiting potentially harmful sites.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9865

Heuristics 4

  • MFA / one-time-code harvesting lure high SE_MFA_LURE
    Document asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
  • 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.
