MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual call-to-action, strongly suggesting a phishing or social engineering attempt. The primary URL, http://netcdn.tw/app/406889139/coin-master-free-spins-and-cards-game-hack, is likely a lure to download a malicious payload. While no scripts were explicitly extracted, the ML classifier's high confidence score and the presence of external URIs indicate a suspicious workflow, likely involving the download of a second-stage artifact.

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.
