MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs and text lures related to obtaining free Robux and game hacks, indicating a phishing or scam attempt. The presence of embedded URLs and the ML classifier's high confidence score suggest malicious intent. While no scripts were directly extracted, the document's structure and content strongly imply it's designed to lead the user to download further malicious content or visit compromised sites.

  • Nyx PDF Classifier malicious score 0.8896

Heuristics 4

  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • 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.
