MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs that lead to sites offering game hacks and free in-game currency, disguised as legitimate download links. The document body explicitly mentions 'How To Get Minecraft For Free On Pc' and includes a call to action to 'CLICK HERE TO ACCESS MINECRAFT GENERATOR', strongly suggesting a phishing or malware distribution attempt. The presence of external URIs and the ML classifier's high confidence score further support this assessment.

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.
