MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and document body text that strongly suggest a lure for free in-game items, a common phishing tactic. The ML classifier also flagged this PDF with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure indicate a potential for downloading further malicious content or redirecting to a phishing site.

Heuristics 3

  • 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.
