MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple URLs and text related to obtaining free Robux or game hacks, indicating a lure for potentially malicious downloads. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest it's designed to trick users into downloading a second-stage 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.
