MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains embedded URLs and a heuristic firing for a malicious PDF URI, indicating an attempt to redirect the user to a download. The ML classifier also flagged the document as malicious with high confidence. The presence of a 'download button' heuristic further supports the conclusion that the document is designed to trick the user into downloading a potentially harmful file, likely an exploit for Roblox.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
