MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF file exhibits characteristics of a link farm, containing a mass of external links to various domains. The heuristic 'PDF_SEO_LINK_FARM' indicates a high volume of links, suggesting an attempt to manipulate search engine results or redirect users to potentially malicious content. No scripts were extracted, and the document body is heavily obfuscated, making it difficult to determine a more specific user-facing lure.

Heuristics 3

  • 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.
  • 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.
