MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document body and extracted URLs indicate a lure for game-related cheats and hacks, specifically mentioning 'Free Robux'. The ML classifier strongly flagged this PDF as malicious, and it contains external URIs pointing to suspicious download locations. While no scripts were explicitly extracted, the presence of embedded URLs and the ML detection suggest an attempt to deliver a malicious payload, likely through a social engineering pretext.

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.
