MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document contains embedded URLs pointing to external resources. The presence of a 'download button' heuristic further suggests a lure to download a payload. The document body and extracted URLs indicate a scam related to game hacks or free in-game currency, likely leading to the download of unwanted or malicious software.

  • Nyx PDF Classifier malicious score 0.9865

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
