MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links to other PDF files hosted across various domains, indicating a link farm or SEO manipulation tactic. The primary heuristic identified a mass external PDF link farm, with the first URL pointing to http://growgreenacres.net/uploads/1/3/0/4/130488851/658bdafb2.pdf. The document body contains metadata and some of the URLs, but no executable scripts were extracted. The overall purpose appears to be directing users to a network of linked content, potentially for malicious distribution or traffic generation.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
