MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.tw/app/406889139/hack-game-coin-master-game-hack', which strongly suggests a lure for downloading a malicious payload. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of external URIs and the overall context indicate a phishing attempt to trick users into downloading potentially harmful files.

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