MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI and multiple other URLs that are suggestive of a lure for downloading potentially unwanted or malicious applications, likely related to game exploits or cheats. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of external links and the document's theme strongly suggest an attempt to trick the user into downloading a second-stage payload.

  • 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.
