MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged for containing a large number of external links, suggesting a link farm or a distribution point for other malicious content. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 32 external links, predominantly hosted on 'www.gorillawalker.com'. While no scripts were extracted, the sheer volume of links points towards an attempt to manipulate search engine results or serve as a lure for further malicious downloads.

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.
