MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a heuristic firing for an external URI pointing to a suspicious domain, and the ML classifier also flagged it as malicious. The document body, though partially garbled, includes text related to downloading Minecraft and a URL that appears to be a download link. This suggests the document's primary purpose is to trick the user into clicking the link and downloading a payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9216

Heuristics 3

  • 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.
