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

The PDF document was identified as malicious due to the presence of a large number of external links, a technique commonly used in SEO link farms to manipulate search engine rankings or distribute malicious content. The document body contains several URLs that are likely part of this link farm, suggesting the primary attack pattern is to lure users to these external sites. No scripts were extracted, and the document itself does not contain overt malicious content beyond the embedded links.

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.
