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

The ML classifier strongly flagged this PDF as malicious, and it contains an external URI pointing to a suspicious URL that appears to be a game hack. The document body, though heavily obfuscated, contains references to game-related terms and URLs, suggesting a lure for users seeking in-game advantages. The presence of multiple embedded URLs further supports the intent to redirect users to potentially malicious download sites.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
