MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button lure, strongly suggesting a phishing or malware distribution attempt. The primary malicious URL, http://netcdn.tw/app/479516143/xray-hack-game-hack, is likely a payload host. While no scripts were explicitly extracted, the ML classifier's high confidence score and the presence of external URIs indicate malicious intent, likely to download and execute a second-stage payload.

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