MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a URL that leads to a site offering a 'Roblox Robux Hack', indicating a social engineering lure for potentially unwanted or malicious software. The presence of ML_NYX_PDF_MALICIOUS and SE_LOLBIN_RUN_COMMAND heuristics further supports the malicious nature of the file. Although no scripts were explicitly extracted, the document body and heuristics suggest an attempt to trick users into downloading an application.

Machine Learning

  • Nyx PDF Classifier malicious score 0.7417

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.
