MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a suspicious URL, and the ML classifier flagged it as malicious. The document body, though partially garbled, suggests a lure related to game cheats or free items, and the presence of a download button heuristic reinforces this. The embedded URL likely leads to the download of a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9432

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.
