MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample was flagged by a machine learning classifier and exhibits a PDF SEO link farm heuristic, indicating a high likelihood of malicious intent. The document contains numerous embedded URLs pointing to external PDF files hosted on 'gorillawalker.com'. While no scripts were explicitly extracted, the nature of the link farm suggests a potential attempt to manipulate search engine results or distribute further malicious content, possibly via JavaScript exploits within the PDF structure.

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.
