MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a clear lure for free Robux, a popular in-game currency, and includes a prominent URL pointing to a potential download. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of embedded URLs and the nature of the lure suggest an attempt to trick the user into downloading a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9863

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.
