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

The PDF file exhibits a critical heuristic firing for a 'PDF_SEO_LINK_FARM', indicating a mass of external PDF links. The document body, though heavily obfuscated, contains numerous URLs pointing to various PDF files hosted on 'gorillawalker.com'. This suggests the primary intent is to distribute or link to a large number of other documents, potentially for SEO manipulation or as a distribution vector for further malicious 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.
