MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded external links, forming a link farm. This heuristic suggests the document's primary purpose is to redirect users to potentially malicious or spam content hosted on external sites. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine a more specific attack pattern beyond link distribution.

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.
