MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a document body that advertises game hacks, suggesting a lure to download malicious content. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of multiple external URIs pointing to potentially malicious PDF files indicates a downloader or phishing attempt.

Heuristics 3

  • 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.
