MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a lure for free in-game items and includes an external URI pointing to a suspicious URL. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest an attempt to redirect users to malicious content or phishing sites.

  • 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.
