MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual call-to-action, strongly suggesting a lure for users to download game cheats or in-game currency. The primary URL, http://netcdn.tw/app/406889139/daily-coin-master-link-game-hack, is likely the malicious payload or phishing destination. While no scripts were explicitly extracted, the ML classifier's high confidence indicates malicious intent, likely through embedded JavaScript or other exploit mechanisms within the PDF structure.

  • 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.
