The PDF document contains numerous embedded URLs and a document body that explicitly advertises a "Robux Hack" and provides a link to download it. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of embedded URLs and the lure text strongly suggest this document is intended to trick users into downloading potentially malicious content.

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.
