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

The PDF contains a large number of embedded links to external websites, as indicated by the PDF_SEO_LINK_FARM heuristic. The ML classifier also flagged this PDF as malicious. The document body is heavily obfuscated and does not provide clear textual lures, but the sheer volume of links suggests a malicious intent, possibly for SEO poisoning or to redirect users to malicious content hosted on the linked domains.

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.
