MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document contains multiple embedded URLs pointing to sites offering free in-game currency or items, a common lure for phishing or scam operations. The presence of a download button heuristic further supports the intent to trick the user into clicking a malicious link. No scripts were extracted, but the overall pattern suggests a phishing or scam attempt.

  • 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.
