MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a link farm with 22 external links, all pointing to PDFs hosted on the same domain. This heuristic suggests a tactic to distribute malicious content or to manipulate search engine results. No scripts were extracted from this sample, and the document body was unreadable. The primary attack vector appears to be the mass distribution of links to external resources.

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.
