MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.co', which are likely used to host malicious payloads or redirect users to phishing sites. The document's content and heuristics suggest a lure for game-related hacks, aiming to trick users into downloading malware. No scripts were extracted, but the presence of external URIs and the ML classifier's high confidence indicate a malicious intent.

  • 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.
