MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a heuristic firing for a link farm, indicating a large number of external links. The document body, though heavily obfuscated, contains numerous URLs pointing to PDF files on the domain www.gorillawalker.com. This suggests the document's primary purpose is to redirect users to a large collection of potentially malicious or spam content hosted on this domain.

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.
