MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that promote 'free Robux' and game hacks, indicating a social engineering lure. The ML classifier strongly flagged this PDF as malicious, and an external URI was identified pointing to a suspicious download URL. No scripts were extracted, but the overall pattern suggests a phishing or malware distribution attempt.

  • 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.
