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

The PDF document contains a lure related to free game items, directing users to a URL that likely hosts a malicious download or phishing page. The ML classifier strongly flagged this PDF as malicious, and embedded URLs suggest a pattern of distributing game-related cheats or hacks. No scripts were extracted, but the presence of external URIs and the ML detection indicate a high likelihood of malicious intent.

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.
