MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a prominent link to 'netcdn.xyz' disguised as a Minecraft launcher download, which is a common lure for malware distribution. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the document's structure and embedded URLs indicate a phishing or downloader attack pattern.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9507

Heuristics 4

  • QR-code redirect lure medium SE_QR_LURE
    Document instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
