T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded URLs, forming a link farm. The heuristic PDF_SEO_LINK_FARM indicates that this is a technique to artificially inflate search engine rankings or distribute malicious content. The ML classifier also flagged this PDF as malicious with high confidence. The document body, though partially corrupted, contains references to these URLs, suggesting the primary purpose is to redirect users to external content.

Heuristics 2

  • 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.
  • 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.
