MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous embedded URLs and a document body that explicitly advertises 'hacks' and 'free items' for popular online games. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of it leading to a malicious download or exploit. The primary attack pattern involves luring users via these links, likely to 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.
