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

This PDF document contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The primary purpose appears to be directing users to a large collection of unrelated websites, likely for SEO manipulation or to serve as a landing page for further malicious activity. No scripts were extracted, and the document body content is largely unreadable binary data, making it difficult to ascertain a more specific attack pattern beyond link distribution.

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.
