MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs that promise free in-game items or cheats for popular games, indicating a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious download site. No scripts were extracted from this sample, but the overall pattern suggests a lure for 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.
