MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent external URI pointing to sites offering 'free' in-game items or currency, indicative of a phishing or scam lure. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of numerous links suggests an attempt to redirect users to potentially malicious websites.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
