MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains numerous embedded links to external websites, many of which are related to game hacks and free in-game currency, indicating a likely phishing or scam attempt. The heuristic 'PDF_SEO_LINK_FARM' and the presence of a download button lure further support this. While no scripts were explicitly extracted, the PDF structure and embedded URIs suggest it's designed to redirect users to potentially malicious content.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
