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

The PDF document contains an embedded URI pointing to a suspicious URL, likely intended to deliver a malicious payload disguised as a game hack installer. The ML classifier also flagged this PDF with high confidence. The presence of a visual download button further supports the lure 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.
