MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for "Robux" and an embedded URL pointing to a suspicious domain, likely intended to trick users into downloading malware. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent. No scripts were extracted from this sample, limiting the analysis of specific execution techniques.

  • 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.
