MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises "how to hack" popular games, suggesting a phishing or malware distribution lure. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URLs indicates an attempt to redirect the user to malicious content or download further payloads. No scripts were extracted from this sample.

  • 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.
