MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.tw', which is flagged as a potential download lure for games or hacks. The ML classifier also strongly indicated maliciousness. While no scripts were explicitly extracted, the presence of embedded URIs and the document's deceptive content suggest it's designed to trick users into downloading further malicious content, likely through a phishing or social engineering pretext.

  • 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.
