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

The PDF file contains a large number of embedded URLs pointing to external PDF documents on the domain www.gorillawalker.com. This behavior is indicative of a link farm, often used for SEO manipulation or to distribute malicious content. No scripts were extracted, and the document body contained mostly obfuscated data and repeated URLs. The primary attack pattern observed is the distribution of numerous external links.

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.
