MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a heuristic firing for an external URI, suggesting it is designed to redirect users to download potentially malicious content. The document body, though partially corrupted, indicates a lure related to 'Free Minecraft Printables' and includes a URL that likely leads to a second-stage payload. No scripts were extracted from this sample, but the presence of multiple suspicious URLs and the ML classifier's high confidence score indicate a malicious intent.

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.
