MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file exhibits a critical heuristic firing for a link farm, containing 32 external links. The document body, though heavily obfuscated, also contains numerous URLs pointing to the same domain, 'www.gorillawalker.com'. This suggests the primary purpose is to distribute links, potentially as a lure or to host further malicious content. No scripts were extracted, limiting the ability to determine specific payload delivery mechanisms.

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.
