T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a significant number of embedded URLs pointing to external websites, as indicated by the PDF_SEO_LINK_FARM heuristic. While the document body is heavily obfuscated and unreadable, the presence of numerous links suggests an attempt to manipulate search engine results or redirect users to potentially malicious content. The ML classifier also flagged the PDF as malicious. No scripts were extracted from this sample.

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.
