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

The ML classifier strongly indicates maliciousness, supported by the presence of an external URI pointing to a game-hacking lure. The document body, though partially corrupted, contains text related to game hacks and a URL that appears to be the primary payload delivery mechanism. The heuristic for a download button further reinforces the social engineering aspect of this attack.

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.
