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

The PDF document contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links are likely intended to direct users to malicious websites or for SEO manipulation purposes. No scripts were extracted from this sample, and the document body contained mostly metadata and obfuscated text, making it difficult to determine the exact nature of the lure beyond the link farm.

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.
