MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, with a primary one pointing to a potential download hosted on netcdn.tw. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a call-to-action phrase suggests a phishing or malware distribution attempt. Although no scripts were explicitly extracted, the document's structure and content indicate it's designed to trick users into downloading further malicious content.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
