The PDF document contains embedded URLs and a document body that attempts to lure the user into downloading a file by promising free game items. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a download button lure further support this assessment. The document also hints at password protection, a common tactic to bypass security filters.

    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.
