MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a lure for free in-game currency, directing users to a URL that likely hosts a malicious payload. The ML classifier strongly flagged this PDF as malicious, and multiple embedded URLs point to suspicious domains offering game hacks. While no scripts were directly extracted, the PDF structure and embedded URIs suggest an attempt to trick users into downloading and executing a second-stage file.

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.
