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

The document contains numerous embedded URLs and a high ML classifier score, indicating malicious intent. The presence of a 'download button' heuristic and a 'password archive lure' suggests the document is designed to trick users into downloading and potentially decrypting a malicious payload. The primary URL http://netcdn.tw/app/479516143/is-minecraft-realms-free-game-hack is likely the initial download point for a secondary stage.

Heuristics 4

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

  • 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.
