MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and text lures related to "free Minecraft Java Server" and "generators", indicating a phishing or scam attempt. The presence of external URIs and the ML classifier firing strongly suggest malicious intent. While no scripts were explicitly extracted, the document's structure and content point towards a social engineering attack designed to trick users into visiting malicious sites.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9447

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.
