MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs disguised as download links for game-related cheats and currency. These links likely lead to the download of further malicious content, such as executables or other malware, aiming to exploit user interest in free in-game items.

Machine Learning

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.
