MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to obtaining free Robux for the game Roblox, directly linking to a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of an external URI further supports a malicious intent. While no scripts were explicitly extracted, the document's nature and the external link suggest it's designed to trick users into downloading a secondary payload.

  • 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.
