MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The ML classifier strongly indicated maliciousness, and the document body contains URLs that are presented as download links for game-related hacks. The presence of multiple external URIs and a visual download button heuristic further supports the conclusion that this PDF is designed to trick users into downloading and executing a secondary payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9969

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.
