MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URL pointing to a suspicious domain, which is likely intended to deliver a payload or redirect the user to a malicious site. The document body and heuristics suggest a lure for downloading an application related to 'Coin Master', a common theme in social engineering attacks. No scripts were extracted, but the presence of an external URI and the ML classifier's high confidence indicate malicious intent.

  • 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.
