MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document's content and embedded URLs strongly suggest a lure for downloading malicious content, likely related to game cheats or exploits. The presence of a download button heuristic and the password archive lure indicate an attempt to trick the user into downloading and potentially decrypting a payload. While no scripts were explicitly extracted, the PDF structure and external URLs point towards a malicious download attempt, likely initiated by embedded JavaScript.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

Heuristics 4

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
