MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains an external URI pointing to a suspicious URL, and a machine learning classifier flagged it as malicious. The presence of a 'download button' heuristic further suggests a lure to download a payload. The document body is heavily obfuscated and appears to be a lure for a game-related hack or cheat.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9874

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.
