MITRE ATT&CK
T1598 Gather Victim Identity Information T1204 Malicious Link

The PDF file contains a large number of external links, as indicated by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, suggesting a link farm or distribution network. The embedded URL 'http://churchoflifeinc.net/uploads/1/3/0/4/130483725/130483725.html#axiometrics+test+answers' is also part of this pattern. The primary goal appears to be SEO manipulation or directing users to potentially malicious content hosted across these numerous domains.

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.
