MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document body contains a lure for free game spins, directing users to download a file from a suspicious URL. The presence of embedded URLs and the nature of the lure suggest an attempt to trick users into downloading a second-stage payload, likely using JavaScript for execution.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9971

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.
