MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a prominent external URI pointing to what appears to be a download site for game hacks or cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related lures reinforces the suspicion that this document is designed to trick users into downloading and executing a secondary payload. No scripts were extracted from this sample.

  • 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.
