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

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs promoting game hacks and cheats. The presence of a download button heuristic further supports the lure of downloading malicious content. The primary IOC is the URL http://netcdn.tw/app/406889139/coin-master-hack-apk-latest-version-2021-game-hack, which is directly referenced in the document body and flagged as an external URI.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

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.
