MITRE ATT&CK
T1204.002 Malicious File

The PDF file contains a large number of external links, many of which point to other PDF files hosted on similar domains, indicating a link farm designed to attract search engine traffic. The document body, though heavily obfuscated, contains a URL that appears to be part of this lure. This suggests the primary purpose is to redirect users to potentially malicious content hosted on these numerous domains.

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.
