MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links and a visual call-to-action button, directing users to download game-related cheats or currency. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs suggests an attempt to redirect users to malicious sites. While no scripts were explicitly extracted, the PDF structure itself facilitates the embedding of malicious links.

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.
