MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains an embedded URI pointing to a suspicious URL, and the ML classifier flagged it as malicious. The document body, though partially garbled, suggests a lure related to free game downloads, specifically mentioning 'Minecraft For Free Games' and including a URL that appears to be a download link. This indicates an attempt to trick users into downloading potentially harmful content.

  • 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.
